Not bad, not bad at all. Mostly very useful, particularly the inclusion of lots more 'software instruments'. Much wider selection of dance beats if that's your thing. In general it fleshes out the obvious gaps in the default material supplied with GB. Nice selection of keyboards, rather limited strings, useful set of synth sounds. Odd plethora of mainly atonal 'atmospheres' which could be used for hardcore/experimental electronic music with a bit of processing I guess, but still hard to see why they're there. Some useful splits, like Piano/Bass, fun to play and sound good. If you're into GB as a scratchpad, I'd say this stuff is essential. Obviously suffers from trying to be all things to all people, but at least there are enough loops to keep dabblers going for a while, or at least until some conversion utilities start to appear.
