Yeah it's tough for me to decide really.
I think the design of the Wiimote wins overall. The speaker is really sweet. It's inovative, sleek and stylish.
For me there is a HUGE improvement from the S-Controller to the 360 controller. The contors are much much smoother and The controller is fitting my hands like a glove. I have really enjoyed it (and the wireless works well on it as well) Button placement feels more natural and those bumper buttons kick ass. D-pad is kinda quirky though. The headset add-on is pretty interesting too.
