Almost two weeks without activity in this thread. That means it is time for a new unpopular opinion! I want to give some praise to a game (or a pair) which is generally unloved and criticized within the fandom, but that I personally like a lot. Even more now that I have gone back to the game and played though it again. I also want to give some criticism to a game which is generally more liked, but that I personally do not think is as great as others make it out to be. I thought about posting this in the likes thread at first, but I think it is more suitable for this thread since it is very unpopular but not completely positive.
Previously, I felt that I could appreciate Sword a lot more after playing L:A. But now, I feel that I can appreciate Sword even more after actually going back to it and playing it again. The game is just so much fun! It was fun back when it was released and it is still great nowadays. I’m enjoying every second of it. In comparison, L:A was also fun but it made me frustrated far too often when I played it. There were so many things L:A tried to do but failed so hard at. It also got many things wrong that Sword and other main series games had gotten right, which was sad to see.
I won’t deny that Sword has some serious issues, the biggest ones for me are dexit and the Battle Tower nerfs. But the game was still fun. Especially battles, I can appreciate the traditional battle system so much more now. Always making your decision for the turn at the same time as the opponent is such a great feature that I will always be grateful for. L:A also has a lot of issues, I have talked about my issues with the game in more detail 
here. The biggest one for me is that the battles in the game just aren’t fun. I really liked the Gym Leader battles and other “boss” battles in Sword, but in L:A, I didn’t like either the Noble battles or any of the trainer battles. Even battling wild Pokémon wasn’t very enjoyable. In the end, both games have their flaws, but while Sword was fun despite its flaws, L:A was often frustrating 
because of its flaws.
Sword also gave me more of a “WOW”-feeling since it was my first Pokémon game for the Switch, thus being my first Pokémon game in HD and the first main series game I could play on my TV. L:A did not give me this feeling. I think I also like the graphics in Sword better than the graphics in L:A. The style in Sword just appeals to me more, somehow. Though I think both of them are good graphically (now that’s an unpopular opinion!).
I have seen some people say that L:A was a big step up from S/S, but I disagree. If anything, I think L:A was a step 
down. It tried much harder than S/S but it also failed much harder with so many of the things it tried to do. S/S didn’t try as hard but they did at least succeed with most of the things they did.
Regarding dexit, my popular opinion is that I do not like it. But that’s not what I wanted to say here. I have seen some people say that we got nothing for dexit, and I definitely agree with that. Even more after playing L:A. While we have gotten Pokémon games that have been fun and enjoyable to play, we had that before dexit as well, so dexit have yet to give us something that we didn’t have before.
So yeah, I can appreciate Sword more after playing L:A. This is similar to how it has been for some previous generations in the past. I could appreciate Gen 5 more after playing Gen 6, and Gen 6 more after playing Gen 7. Oddly, I have yet to feel this way for the Alola games despite being a fan of them. I’m not sure why. Maybe I just overplayed the Alola games so much when they were new to the point that I have yet to miss them. Or maybe it is because they failed in some aspects which I consider very important in Pokémon. I’m not really sure. I still like them and Gen 7 is still my third favorite, I just don’t feel that I can appreciate S/M and US/UM more after playing Sword and L:A.
Now to another unpopular opinion, related to the above. I really like the story and characters in Sword. Like with the game itself, I have come to appreciate the story a lot more after replaying it, and I definitely prefer the story in Sword over the one in L:A. I like how the story in Sword was a bit more light-hearted and down-to-earth compared to the more extreme stories of previous games, especially Gen 7. I liked the stories of the Alola games as well, but it was nice to get something different as a change of pace.
I like how there are basically two stories told alongside each other. First the player’s journey to complete the Gym Challenge and beat the Champion, then the story of the legends and Sonia’s investigations. They then come together at the end and the final battle against Eternatus is one of my favorite moments in the series. Teaming up with your rival and the cover legends in a battle against a powerful opponent is one of the best battles in the series.
I like the DLC stories as well. The Isle of Armor with Kubfu, Mustard, Honey and Klara/Avery, as well as the Crown Tundra with Peony, Calyrex and the other legends. Those were great and fun to play through.
I really like the characters too. The rivals are all splendid. Klara is fantastic, Hop is great, Marnie is good and Bede is pretty good too, I like him better than I did earlier now that I have replayed the game. He was better than I remembered. I haven’t played Shield so I don’t know about Avery, but from what I have seen, he seems to be on the same level as Klara. Most of the other characters like Sonia and the Gym Leaders are great too.
One recurring theme in the games is succession and growth. Many of the characters get new roles over the course of the game, like Marnie and Bede taking over as Gym Leaders, Klara/Avery also becoming Gym Leaders, Sonia becoming the new Professor and the player character taking Leon’s place as the Champion.
The story had some issues though. I think Rose’s plan was rather stupid, it could have had a better execution or it could have been something different altogether. But overall, I really enjoyed the story in Sword.
I liked the story in L:A as well, but it just didn’t resonate with me in the same way as the story in Sword did, it didn’t leave a big impression on me either. It was okay, but not super great. I disliked how the player was portrayed as “the chosen one”, picked by Arceus to travel back in time to save Hisui. I would have liked it better if the player had instead been a young new member of the Galaxy Expedition Team who later gets picked by Arceus because of their actions and kindness towards Pokémon (or something). While this would have caused problems later on when Kamado believes the fault with the space-time distortion lies within the player, I think it could have been solved in a different way without too many problems.
Still, there’s a lot I like about the story and characters in L:A. I absolutely love how Ingo was brought "back" and his role in the game. I think Volo was a great twist villain, I also like the rivalry between Adaman/Irida and their clans, as well as the romance between Iscan and Palina. But on the whole, it just didn’t leave a lasting impression on me. Overall, I think Sword is among my 5-6 favorite stories in Pokémon games, while I think the story of L:A is good but only slightly above average at best.
So in the end, I definitely like Sword better than L:A. Sword is far from perfect, but it is still a really fun and enjoyable game. It is my 6th favorite Pokémon game on the whole. I still think L:A is good, but Sword is really great. I’m not sure if I will get any future Legends games because of all the problems I had with L:A, but replaying Sword has definitely made me appreciate the regular main series games more and it made me a bit more hyped for S/V!
