Windows Phone 8X for Verizon

So I'm able to upgrade for Verizon in about a month, and I have some questions about the Windows phone 8X. I've been reading posts lately saying that it lags and whatnot and I wanna ask owners if they see it. Also, should I buy the 8X or wait for some other one?

FYI, I currently own a family member's old Droid Incredible and I hate it. I have an iPad mini (love it!) and would like to give Windows Phone a try.
