GameCube is the only Nintendo console that never had a truly great Mario platformer or Zelda and even Mario Kart was a little weak.
I think based on that alone it can't be tops. For me the GameCube was kinda like when you order a Coke and the waitress accidentally brings you a Diet Coke ... it tastes similar, but something is just off.
That was the GameCube to me. The Fisher Price design was silly (and pointless) too, along with a lot of bizarre arbitrary decisions -- only one Z-trigger? Why? Because. Only a tiny little d-pad. Why? Because. No online games even though we have a broadband adaptor. Why? Because. We have Resident Evil exclusivity but we've Toon Shaded Zelda. Why? Because.
At least with the N64 you could say they made a big mistake in misreading the shift to CD-ROM, but otherwise most of their decision making was on point and quite innovative (Rumble Pak? Yes. 4 console ports? Cool. Analog stick? Yup).
