I can say the same, I tried the 360 for the first time a few weeks back.. I felt the controller was complex for some reason.. I don't know why, I mean I have played a lot of PS3 and I'm fine with that controller..
Anyway I tried playing gears of war for about 4 hours.. Didn't like it.. Controls were not precise enough for me..
So I guess I'm used to the Wii as you are used to the 360.. But you don't see me making a thread about it.. Just personal tastes..
