Well, technical stuff aside (GameCube > 3DS, but 3DS can do more modern techniques), I'd say it's a mixed bag. GameCube wins at some points while 3DS wins at others. It's quite balanced actually.
Both Luigi's Mansions and the Mario's look quite comparable. On one hand we haven't seen things like Rogue Squadron and Twilight Princess on 3DS, but on the other RE: Revelations exists.
