Except I'm assuming you look at these on a white background, and not something darker like dark theme on here or on an actual simulator:
I'd say the outlined one fares better here, but the difference isn't that huge. But, with Conkeldurr:
It really shows how all its details wash away without any sort of outlines + the white artefacting you get when making these in to GIFs. And with how transparent GIFs work, you really want this sort of antialiasing matte present for anything that isn't straight up pixel art, as without it it would make the transparency look incredibly choppy. It's like GF made the models with outlines in gen 6 & 7 for a reason: it was on a smaller screen and resolution so you needed to make them pop out more, sort of like how this translates to the GIF versions we're seeing now. The models + textures used on the Switch weren't made to be presented this small. Exporting the footage in to animated PNGs instead of GIFs could theoretically fix the antialiasing matte issue, as it's a much more modern file format when it comes to handling transparency, but it's a cumbersome format to create and still isn't supported by all browsers.
DJTHED was looking in to the possibility to
render the models directly with the kind of outlines used on the 3DS, instead of this outline filter that's being used right now, but it's still waiting for the animations from the games to be parsed atm afaik.
Basically I don't see any reason to use non-outlined variants, as they don't work well in this small format.
