@matana @BJay i only say gumball is the most unique out of all of these, btw, because it employs a lot of different techniques of art and blends them together really well. you have 3d rendered backgrounds, some 3d characters that have a sort of stop-motion look to them, a lot of absolutely insane facial emotion.
it also came before most of the shows on here so it gets a pass based on that alone. gumball never felt like it was copying anything. the show as a whole has a very specific shitposty nature about it and that doesn't show just in the humor but the art as well. the rest feels just, super generic.
gravity falls has some really pretty backgrounds, and predates a lot of the shows there too.
