I personally didn't noticed much difference from official release. but some people comment it being faster and better.
I did noticed this build is compiled with newer version of tools, probably on a 10.5.4 (!!! I know, I know) machine.
If you are using leopard, you probably will see more significant improvements. If you are using Tiger... hey, doesn't hurt to try out!
PS. another opt builds can be found at http://firefoxmac.furbism.com/ which offers G3, G4, G5, and Intel builds
