I've really liked the asymmetric layout on the GCN and 360 controllers. The dualshock's sticks were definitely a rung below the 360's in my opinion. That may be more about their lower placement and personally poor ergonomics on the handles than the fact that they are symmetrical, though. The WiiU is symmetrical and I don't mind it.
I still think asymmetry is more fun!
Haven't had a chance to try either new gen controller.
