Honestly I think Xfce is about the same. And probably more stable, though obviously it's hard to do a direct comparison.

Depending on the "Distro" and compile options/build flags/included libraries MATE is as fast and light, since at least 6 years, actually. I think the first distribution which showed that to a general audience was LMDE a.k.a. Linux Mint - Debian Edition.

The window chrome is fine but the settings are a bit of a mess in my opinion.
