I find the Licensed Floyds always having poor quality, the metal is usually softer and some go out of tune really fast which I really hate!
The OFR is made by Schaller I believe, but had a little different feel. It was a little easier to handle. My KE2 has an OFR right now and I love it, but it never goes out of tune because of the Rockinger Blackbox which was installed. It's now a little tougher to handle but sustains better!
The Kahler is my favorite. Has the best sustain, can be handled a lot easier and always seems to stay in tune.
Also another recommender is the Lo Pro Edge from Ibanez. It's a little smaller, but it is harder to handle compared to the OFR. It's very solid though, doesn't seem to be a cheap knock-off. I like the OFR better, but some people find the LoPro Edge to better or equally good
