I'm not a fan. Got this a week after it was released. Battery life is horrid, gets hotter than a witches tit with a brass bra in the summer time and often lags. My Note 3 is faster, it seems.
On Lollipop, my battery life is about 3 hours. Keeping in mind that I'm a power user, I still think its crap. Yet, my Note 3 running Kit Kat gets about 5 hours. :-/
