In your experience, what's the distro that was the most stable and had the best performance?

I was just wondering, what's the distro that has been the most stable and had the best performance for you guys? With Quote:

stable

I mean that It had the less bugs, crashes etc. and with performance I mean best file I/O, best graphics performance, best CPU performance (compiling, rendering etc.). And If there wasn't any distro that combined these two, what were the two that had these two.
