I do not have the one, but the evo 3d. I have been running aosp jellybean 4.2.2 and have to say I do not miss sense at all. I have been contemplating the Nexus 4 as my next device because I love the stock android jb and can't fathom being locked into sense again.
You can see that the All Things Root section is pretty small for this device and it sounds like s-off is unavailable. If I were you, I'd be worried about getting stuck with a phone that has limited development. What if you hate sense? You may not have a 4.2.2 aosp rom available.
Just something you might want to consider/research a little before jumping ship
