Not considering the novelty/exclusivity, talking purely from the perspective of end usage, I guess I prefer the subtle additions done by Samsung. The S-Pen is a huge benefit in my case. Also I somehow expected the screen to be a killer which unfortunately isn't when compared to the Samsung. Also the non-expandable memory is a big downer for me. Not that I'll always have the available 13GB filled up to the brim, I still don't like the feeling of being constrained.
I do like the stock look but I guess it felt better on the nexus 7 than on the nexus 4. I was actually thinking of replacing the NOTE-2 and Nexus 7 with the nexus 4 but realized that that wasn't a great thought.
