I've been using it all day and I'm impressed so far.
It's very responsive and the screen is amazing.
The battery life is also amazing. If I'd used my old phone as much as I'd used this one today, it would have been choking for power. My Note 3 barely got to the low 80's.
I also spent some time reading comics on it as it was a great experience. I would never do that on a phone and while I would prefer a larger screen, reading comics on the Note 3 was very enjoyable and much more convenient.
