Well I don't like it either but it's smoother than windows:|
That's not necessarily true. You just assume it is.
I could write longer about problems under the hood and how stupid the interface is but the most glaring problem is that none of my apps are running well on it...Maya 2012 won't even install even with Direct Connect turned off and ZBrush 4R3 and Topogun won't start!
I'll stick with Snow Leopard. I also want to compare the benchmarks because I swear the new i5 3.1Ghz iMac is running SLOWER than our Core 2 Duo 3.04 Ghz.
Did you update to the latest? Zbrush should be fine.

9. What version of Mac OS X does Autodesk use in the Maya graphics certification process?
Maya 2012 graphics certification testing was done using Mac OS® X v.10.6.6 unless otherwise specified. Autodesk recommends that you use the same operating system version that was tested with the graphics hardware. A newer version does not always provide the best support.
I'm not sure about topogun. Maya 2013 was probably tested on Lion.
