Beautifly is definitely cuter but Gen 1 has a certain level of charm. Like, Beautifly is almost exactly the same as Butterfree. The concept is the same. And I know that we have duplicates of animals in meat space but their individuality is important in Pokémon and doubling up with that (and making a sword pokemon are you kidding me) just diminishes their value.

But hey, some of them can be cute.
