I still prefer the 360. I hate the UI, and there's too many things I hate about it to list. I still get these weird sound problems, where you'll hear a loud snap, and then it continues to echo until you have to do a hard reboot. It's happened with all of my games, and it seems to happen with a lot of other people, too. I sometimes get booted out of my games for no reason. The loading times are surprisingly really bad for most games I've played. I've played 3 different games on the 360 that are also on the X1, and when I played it on the X1, it took about twice as long, if not longer, for things to load up, but of course, they do look better. But at the same time, you're prone to sound and graphical issues.
I dunno, I think the system is a step back. Sure, it's more "powerful" than the 360, but overall, it feels like I'm playing a prototype system that isn't ready to launch for another year or two.
