For the most beautiful DE, it's so... meh. It's a shame. Does anyone here remember Beryl? Now that was mindblowing stuff, still can't wrap my head around the fact it's dead...
Oh right, I forgot all the cool things I had enabled on Compiz: live zoom, wobbly windows, the burn effect. Transparent windows! Those were great. The cube, of course. The shift switcher. Expose.
There's still an active Compiz fork, I think; Beryl merged back in, it didn't really die.
Perhaps wayfire[0] can fill the compiz shaped hole.
