I wish 4X was good. But alas he sucks. I love his personality and his story. I'm a gunnery spec and I've used Dorne since the moment I got her. She is the clear choice. It takes me only 10 more seconds to kill all level mobs(standard, elite, boss) but I always come out of fights at full health and full ammo. With 4X he would usually be almost dead at the end of each fight and would almost certainly die on boss fights.
