I asked myself that and ended up with the Nexus. I do stuff you'd think the S pen would be good for - quick technical drawings and schematics and so forth. But I have found that the Bamboo stylus is fine for that and the better resolution of the Nexus helps my work. Also it sounds better when streaming movies

I like the grippiness of the Nexus too. This is from a Samsung fanboy.
As for the resolution - where this really helps is in resolving fine lines. It's impossible of course for a screen like this to be blurry. What it can do is fail to resolve edges well. If the screen driver can't decide cleanly where a pixel ought to be - for instance if you draw a 1 pixel wide line in the space BETWEEN pixels - the software has to decide what to do. Say the line is vertical, but very slightly tilted. The software will light whichever pixel it decides is right, then the next one up the line may end up closer to the next pixel and it will light that one, or it may light both. So you end up with what appears fuzzy. Finer resolutions don't eliminate this (since finer <> infinite) but it does make it less obvious. The Nexus screen is beautiful and makes technical drawings look much better and easier to read. For stuff like movies and so forth, it doesn't matter to me. The motion covers up any pixelation.
The point, if there is one, is that both tabs are really good. They have different feature sets and strengths. I find the Nexus better suited to my use. But there is no question that Samsung makes a heck of a tab too, and somehow I got along on a lesser screen (Samsung Galaxy Tab 10) before the Nexus came along
