I don't personally like leather because it retains moisture. In Kydex, you've got three really good choices. CompTac (one caveat: clips tend to break if you're rolling around on the ground grappling), Bladetech (I use the UCH, as does my LE fiancee), and Raven Concealment. I haven't worn a Raven personally yet, buy people that I know that carry CCW professionally have given them high praise.
