My fondness of the UAG Navigator is starting to waver a bit. I am realizing it makes the phone quite a bit more wide, almost to the point I don't like the way it feels in my hand. As odd as this sounds, I might go back to the hyperion extended battery and case (newer style) as that feel is about as solid as I have found when it comes to cases on the Note 2. Plus, for about one milimeter difference, I am packing a 6200mAh battery, and the phone is quite a bit less wide in my hand. The attached photo shows the height difference between the hyperion and the UAG.
I handled a lot of cases for comparison, and have noticed with UAG bumper is not as rounder around the outer edge. That creates a feeling of it being wider by a probably 1mm or more when in your hand. Personally, it doesn't bother me, I don't have the biggest hands to begin with. I have been through slimmest Case-Mate to widest Defender and everything in between with premium and ebay cases. Because the outer shell and sides of UAG made out of hard plastic which feels a little on a slippery side to handle (and it will wear off with time), this bumper outer edge makes a perfect GRIP when you handle the case. There is no question about added protection which gives you a piece of mind, but extra grip is definitely a bonus with outer edges being rougher and flat rather than inward rounded.
With regard to other question posted about Commuter and Ballistic comparison, UAG will be the lightest and easiest to use because it composite one piece rather than inner and outer shells like the other two. Level of protection will be the same due to a decent lip/bumper, quality plastic shell, and better quality inner rubber material. With reference to grip, Commuter will be the worst with all around slippery outer shell (both in your hands and easily slides with you put it on the surface). I never handle Ballistic, but from other reviews out of the box it will be less slippery in your hand, but as I mentioned above the design of UAG lip/bumper compensates for a better grip, IMHO. I know you can probably smell my biased opinion, but I'm also trying to be fair
