I own both, as well as a Wilkinson/ Gotoh VS100 strat-style bridge (with the same arm holder), and an OFR with their new gotoh-style arm holder.
They're all awesome bridges, and in fact I'd wanted a Gotoh arm holder for my OFRs and Ibanez since pretty much the moment I first tried one. The tension-adjustable bushing is hands-down the best design I'd tried, when I threw the VS100 into my strat.
Between the Edge and the Gotoh, feel under your hand will differ slightly, but they both perform very similarly. I'm trying to think if there's anything I can think of where the Gotoh doesn't measure up to the Edge, and I can't really think of anything - the fact that technically the bar screws in, as I recall, may be about it, meaning you have slightly slower bar installation/removal. It's a fair trade, though, because Ibanez bushings wear out so quickly, and don't really let you adjust the amount of play in the bar.
That said... Don't rule out an OFR, either. Here in the states, at least, it costs less than either an Edge OR a Gotoh, and while the bar design IMO was never as good as Gotoh's and merely annoying in different ways than the Edge, their new pop-in bar is awesome. Unlike the Gotoh (and, like the edge) it literally just pops in to the arm holder rather than screwing in, but it employs the same sort of tension collar with an allen key to increase or decrease rotational resistance. It's also a cheap upgrade:
Unless there's some reason you DON'T want an OFR (the lack of locking bushings is the only thing I can think of, though this isn't as big a deal as you'd think - Floyd uses a MUCH smaller threading than the Edge, so there's not much play in them to begin with. I've never actually taken the studs out on the Gotoh I have, so I can't tell you how they compare, I'm afraid). As it stands, I know you can put an OFR arm into an Edge, so it's just a matter of time before I try putting a pop-in OFR arm onto the Edge on my 550. It's just a far better design.
