I don't think anybody claimed that the Mac is better at editing when it comes to cross-platform software like Adobe's Creative suite. People generally buy Macs for editing if they want Apple specific software like Aperture or Final Cut. Personally, I liked the way OSX works and I while I prefer the value of raw power of PC hardware, I am for now, unwilling to go back to Windows to get it. I got a Mac because I prefer OSX and in this case, any editing software I got followed that decision.
There is your answer Razvan.
