The 64 controller is actually brilliant for some games like GoldenEye. No other controller plays them better.
The GC has Rogue Squadron 2 and Metroid Prime and certainly some other great games.
The GC also has rpgs like Baten Kaitos en BK Origins, Sky of Arcadia Legends, Tales of Symphonia and Fire Emblem.
I go for the 64.
