I have always wanted a Kahler, and when I make my partscaster, if I can afford it, it will have a Kahler. The only problem i've seen in them is they like to go out of tune after a lot of bends, but if you do a small dive it goes right back in tune. I haven't tried a guitar with a Kahler unfortunately, so I have no personal experience with them, just what i've seen in videos and reviews. They are extremely adjustable, they take a lot less wood out of the body, and would probably retain a lot of the "tele twang" because of the mass of the bridge. So if you want to put one in a Tele (like me) it may be a better option to retain the tele tone than a Floyd.
