It's definitely worth it! I got my 925 in late February and came from a 920 and 810 before it. As I type this, I actually have my SIM in my new AT&T unlocked HTC One that I'm using on T-Mobile (I just became obsessed with giving Android a try and fell in love with the One), but I'm swapping it back to my 925 later today because it's my daily driver bar none! If something should happen to that phone, my daily driver would be my 920 again. Around a year ago, when I was still using my 810, I swapped the SIM out to use my iPhone again but couldn't last longer than a few minutes - so I definitely understand your temptation to switch back to Windows Phone. It's just the best OS out there!
