I'm a straight grip kinda guy. Mostly aesthetics, but I can think of a couple of advantages. There is less wood in a straight stock and it makes the rifle a bit lighter. I don't carry a lever gun with a strap, but in my hands. My right hand is at a more natural angle with a straight grip vs pistol grip. At least while carrying. I'll concede the pistol grip is a little more comfortable to shoot and cycle the lever. But I carry it a lot more than I shoot it.
