>>41020584>>better musicSubjective
>>better world designWhile DP had a shitton of HMs and RS were rudimentary, XY's world only forced you to use HMs like strength for optional routes, and SM finally killed HMs. This alone makes them better, but you could also add things such as a better scaled world in SM or being in actual 3D on XY if you care about aesthetics
>>evil teams are betterTeam Skull is one of the most charismatic teams in the series, and Team Flare's boss had a more understandable goal than "flood/burn the world" or "erase everythng lol"
>>sprite work looks a thousand times nicerThey were garbage compared to Crystal's sprites, hell, they only had 2 real frames of animation. XY had ALL new 3D models AND it still managed to have just as much content as 2D games
>>no framedropsEasy when you barely have any animations, though I admit that SM's totem battles were awful
