Mountain Lion uses like 300mb more on my Macbook Air (probably some of the new stuff running in the background like Notifications) but I don't feel the difference in performance. It's not much slower or heavier than SL during real world usage. It does on the other hand feel better than Lion (I really had regrets when I first switched to Lion, particularly before the bug fixes). But I don't think Lion's problems had anything to do with ram management. Some of the animations just felt particularly sluggish, even if the computer had lots of ram free, and lots of other little things like that. By not switching to lion and waiting for ML you dodged a bullet.
