I purchased an XP-12 in December 17, and was very happy overall with the sound.
Incidentally, the Pass XP-22 dropped right after I purchased the XP-12, and was tempted.
When I inserted the 22, I found it to just be a better version of the 12. Last generation, the 10 versus the 20 was as much about slight tonal changes as improvement, with some people preferring the 10.
With the 22 over the 12 you get just more of everything great. Blacker background, more details, tighter and more detailed bass, and a little larger soundstage.
I felt the upgrade was worth it, and am still rocking my 22.
