'Vicar; mwah is to be found more in setup and technique that any particular instrument-at least in my experience.
You want to set the trussrod so the fingerboard is as flat as you can stand it, then set the action real low. You'll have to have good right hand technique to go as low and flat as possible and not just have things rattling around.
Having said that, I have two G&L fretli, they work well...:
