>>55654746BW stands on its own better and was clearly less rushed than B2W2.
BW managed something that no other game did except gen 1, it created a whole new ecosystem with only its own new pokemon. And it did it better than gen 1 in some sense. Gen 1 only had 15 types, BW had 17 and yet it managed to distribute them better to the point where every type has enough representatives for a playthrough, something that no other game really managed before it since even Platinum kind of lacked dragons and Hoenn lacked ice. BW is what every fakemon rom hack aims to be
Now compare that to B2W2 which spams fan service mons on routes, most of the content it added is fan service too like PWT, gives you free shinies out of nowhere, has reused dialogue despite being a sequel NOT a third version... and has the worst implementation of difficulty settings in pokemon history.
A problem BW had was that important trainers didn't have enough pokemon, because of the limited dex. B2W2 could have fixed that since it has a bigger dex, but it didn't, instead it locked the bigger teams behind a post game locked, version exclusive hard mode that doesn't even work as intended
