Azumarill's Advantages:
1. Better bulk Azumarill's bulk is really good for an offensive Pokemon and can easily take most neutral hits. Crawdaunt on the other hand, has the defenses of a wet tissue paper.
2. Better defensive typing Azumarill's Fairy typing gives it resistances to common Fighting and Dragon type moves. Crawdaunt on the other hand, doesn't gain any notable resistances over Azumarill considering even resists hits Crawdaunt hard.
3. Easier to sweep Azumarill has access to Belly Drum, while Crawdaunt only gets Swords Dance, which means Azumarill hits harder than Crawdaunt given 1 turn of set up, and also sets up more easily even considering the fact that it needs 50% of its HP to BD.
Crawdaunt's Advantages:
1. Hits harder Crawdaunt hits considerably harder with Knock Off and Crabhammer, allowing it to break walls more effective than Azumarill.
2. Better offensive typing Dark/Water is resisted by less common Pokemons than Fairy/Water, meaning that Crawdaunt can spam its STABs more often than Azumarill without getting walled, so it can rely less on prediction.
3. Ability to set up more than once Azumarill only has the opportunity to set up once so it only has only one chance to sweep. Crawdaunt is given more chances to attempt a sweep if forced out.
Conclusion:
Azumarill is generally a more defensive Crawdaunt, and being reliable in most cases given its better defensive capabilities. Crawdaunt on the other hand, works as a better wallbreaker for its raw power over Azumarill. When deciding between the 2, it is important to know what you need it for. If it is for the sake of having a physically offensive water type, use Azumarill; if it is for breaking walls for something else to sweep, or for punishing switches, then use Crawdaunt.
