@Wildchildnumber2: would be easier for you to tell us which licensed trem you want to know about. Meanwhile, I'll try to break down to you my opinion/experience/research on trems.
As far as Jackson is concerned, their licensed tremolos are the worst amongst all the "big brands" (Jackson, ESP, Ibanez, BC Rich, ... [I have not mentioned Fender nor Gibson because of the massive lack of floating bridges in their catalogues, don't jump on me for that]). Notable exception to be made with the one on the RR24s (not sure if other models share it) which is buit to the specs of the OFR but in Korea. It's no OFR but works damn well and keeps tuning stability great.
ESP's I don't know but they seem to make pretty decent ones.
As far as Ibanez, Edge IIIs are love it or hate it. E.g. IIRC Swabs here hates them, but other people like me or Nick like them and find them awesome for the price. High end Edges (Edge Pro) are neat. Still don't keep tuning as stable as the OFR I think, but maybe yes and I did a bad setup. Nonetheless, the tuning stability of those is great. And with the Zero bridges, tuning stability is just perfect with their system, only downside beeing the actual tremolo action. Maybe it's me, but I don't really like the arm on those, feels quite loose always.
Depends, they're all different. Some are somewhat consistent in terms of tiers though, e.g. Jackson and ESP licensed Floyds, whilst (sometimes) adequate, are usually not particularly good over time, Schaller licensed Floyds are brilliant, due to Schaller themselves making the best quality OFRs. And of course there are Ibanez Edge tremolos which are pretty much in a class of their own, really stable. I'd go so far as to say that the Edge PRO is superior to the original Floyd.
now the guy with the fixed bridge nows all about floating tremolos!
"due to Schaller themselves making the best quality OFRs", "I'd go so far as to say that the Edge PRO is
superior to the original Floyd": get your head out of your ass! You've owned none (no, trying in a store for 20 minutes is not creditable) yet you talk like you had played all for years. Nothing takes over a real OFR. If you like lower profile trems then you may prefer Ibanez Edges (Edge Pro), but as far as tuning stability, built, working and overall performance an OFR is hands down king on floating trems.
