Hmm hard to say, but I would say Gamecube edges out a bit more than the Wii, but this might be reflection of my tastes. For Example N64 edges out the Gamecube and Snes edges out N64. Same with Sony consoles, given the PS4 is pushing upwards over the PS3 (might help that I don't own the twin console this time around).
The only trend I saw go upwards is that I enjoyed 3DS a bit more than my DS which I enjoyed loads more the GBA and GB/GBC.
