"Has Mountain Lion been feeling faster for you compared to Lion on the same machine?
It's probably not just you: Mountain Lion appears to include improved graphics drivers and low-level graphics subsystem improvements. According to our testing, these improvements result in an approximate performance increase of up to 10 percent. Those improvements can make your current hardware feel faster despite the fact that your CPU can't magically crunch numbers any faster. The changes also lay the foundation for Apple to update OS X's OpenGL support in a more timely manner, which could potentially lead to better graphics performance in the future."

With Mountain Lion I'm having a total different experience, It is fast, stable and very polished.
In a nutshell: Mountain Lion is what Lion should have been.
That was my first impression when I installed Lion - the feeling that it was always rough around the edges but I kept making up excuses that maybe a 10.7.x release will address those problems but alas the problem was never really addressed. Mountain Lion for me was the first 10.x.0 release where I actually felt happy after installing it - I just hope that with the move to LLVM/Clang and the better debugging tools that we'll see improved code quality and thus more refined 10.x.0 releases to come.
