I much prefer it, I perhaps should have tried Snow Leopard with the extra RAM a while longer. I didn't give it much time to grow a fair comparison. I personally love the new UI, the dark theme is fantastic. A little disappointed the Dock background isn't translucent though. Only issue I've had is getting used to Mission Control, putting the windows in Split View and then having them move to a new "space" was pretty jarring at first, having been used to how Win7 works them.
