I had quite a few myself...
Mogul, Touch, Touch Pro 2, Hero, EVO, Inspire, MyTouch 4G, Sensation, One M7, and now One M8. I might be missing one or two in there somewhere.
To be honest, I haven't been very happy with any of them other than the M7, my EVO, and now my M8. The rest of them all had plenty of issues that made me reluctant to get the M7 originally. In fact, if it wasn't for the fact my roommate wanted it and then couldn't figure out how to use it and had me trade my S4 with him, I never would have had another HTC product.
If I've helped you, please remember to thank me!
