All in all, 7th Heaven is much better than Bootleg. You have more options (aside from Cloud's weapons) and you don't have to waste space on stuff you don't want.
Plus it uses Aali's OpenGL Driver 8.something (I forget the specific version) instead of 7.11.b, and vgstream instead of FF7Music.
Though, in reality, you should probably try to customize it specifically to your tastes, with external mods as well (as long as they're compatible, of course).
