I love the untucked look because I equate it with rocks and rugged terrain. The exposed lift, the bigger tires, the wider stance. All of it makes me say, "Aww yeah."
The full fenders I usually equate to overland Wranglers, or, more obviously, stock Jeeps. The overland Jeeps makes me nod to myself and wish I had a month off to just travel the country and live out of the back of it.
That being said, I've always liked the full fender, but I'm voting for flat.
