I've been using the Wii U Pro controller with the Mayflash adapter. Mainly because I like using a Nintendo controller for Nintendo games since the ABXY buttons aren't jacked up like they are on a 360 pad. I'll eventually get a GCN adapter for my Wavebird just for a pure feeling when playing, but I honestly think I'll stick with the Wii U Pro for awhile just for the better, bigger d-pad (which helps in Resident Evil Zero and the RE1 Remake). Plus, the battery life is loads better than the 360's or PS3's. I went 2 months of heavy gaming with no charging -- and this was how it was new out the box. I literally just had to charge it this past weekend.
As far as mapping goes, L&R are L&R on the Wii U Pro while Z is ZR (the trigger). It's a solid pad, so I'd give it some consideration. I use it for NES and SNES as well (SNES is LOVELY with this pad).
