The base design is probably my favorite. The Ultra ball is probably next. The lure ball is really neatly designed, with it's symmetry and contrasting colors. The Premiere Ball is pretty in it's simplicity and the reverse of the regular ball. I have a soft-spot for the Luxury Ball, because I thought it was funny my little brother used it to catch his Groundon in Ruby, back when the games came out. Master Ball is neat, but something about it's horns bother me; same goes for the Great ball. I like my Pokeballs to be 100% spherical.
