The controls aren't perfect, but I like 'em better. The system has the Classic Controller also so, contrary to some thinking, Nintendo didn't abandon that type of control. IT will be in SSBB right?
But for aiming the wiimote easily wins. There's a mechanic the other controllers can't copy. Fast twitch aiming.
The motion control also made all the WiiSports game unique and fresh and more entertaining. Again unique.
I think for Mario Strikers, which is more traditional type of game, it wins too. I like holding my hands apart for one thing. That's big right there. It's just more comfy. Second the subtle Wii-specifc controls add a nice flavor to the game. The jerking of the wiimote to tackle adds a visceral feeling to the game. Pointing to block MegaSTrike shots is quickly understandable yet fast paced and challenging. Jerking the nunchuk to distract the other guy doing a MegaSTrike or to switch PowerUps lets you perform these moves without taking your hands off the controls.
I did miss camera control in ZElda:TP. But I got used to it. I mean camera control is often a minus as much as a plus anyway.
