Subjectively speaking, the story is fucking awful. I hated Sun and Moon but at least that game had memorable characters, in Sword and Shield their only memorable trait, if any, is being attractive. Wild Area is extremely underwhelming in terms of size; it's a nice idea but there's nothing to explore and you'll have seen all there is to see shortly after reaching each half, and the Wild Area itself only goes through half of Galar, with the back half just being a bunch of direct shots between towns to rush you to the end of the game. Dynamaxing as a mechanic sucks, it barely effects the difficulty in singleplayer but is completely broken in the hands of anyone with an actual strategy, making the VGC nothing but sweepers and stallers in an even more stale meta than gen 7. The music is fucking dogshit too.
The only thing that isn't a downgrade from Sun and Moon is that there's more character customization options, but even then it's nothing noteworthy compared to any other game with character customization and once again the males are fucked over in terms of variety compared to the females.
There is no good reason to buy these games, just play a fangame or Showdown and you'll have a much better time.
