A few years ago, I've switched over from DD-WRT to Tomato and I haven't looked back since. Before I did, I poked around with OpenWRT but found it too confusing or annoying to use (and I'm a CS major and setup and configured Linux servers using SSH).
I'm probably not going back to DD-WRT because of all the controversy but I was wondering how X-Wrt is nowadays? From the screenshots, it looks a lot more featured packed than Tomato and that definitely has its appeal. Then again, simplicity has its advantages to.
