Well I installed a German Floyd on a guitar with a brass block upgrade, and a Gotoh Floyd in another.
The German Floyd sounds pretty huge, but a big part of that is the oversize brass block. But I also had a few issues with it. The saddles rattled a little bit from touching the one next to it...had to tighten them down perfectly in place. Also, the break angle of the string coming off the saddle itself was a little sloppy and one string vibrated on the saddle and wasn't sitting down tight on the saddle due to the angle of the saddle. But other than that, it sounded giant and worked great and looked cool.
The Gotoh didn't have those little problems, which made it a bit easier to get set up and rolling. So I definitely dig that. Maybe an oversize brass block on the Gotoh will make it sound as big as the Floyd did.....we'll have to try that next time.
So I like them both, with the gotoh having fixed a couple of the small issues the German Floyd had. But there is also something about the original Floyd and just the way it looks....complete classic. Oh well, they're both great!!!
