I actually like almost the entire set. The colors are very vibrant, en Ken Sugimori’s artworks are great overall. But if I have to pick some favorites:
And the best of course: Nude Misty! rofl 
I actually like the English version next to it much more tbh…
As for least favorite I can’t really name any tbh… Except maybe some of those City Gym Trainer cards…
