>>46460931B2/W2 was the most complete of the 2D ones, with PWT being a good send-off to the era of good games, and Crystal was the best one for nostalgic reasons, vastly superior to the gens before and after it (besides Emerald). Even genwunners prefer the stuff RGBY introduced, but not the games themselves.
Though speaking of nostalgia, I personally prefer Silver, since Crystal based its sprites over the uglier Gold ones, and introduced visual changes I didn't grew up used to, but I agree it's overall superior.
