Speed and memory are really unrelated to OS; they are dependent on the hardware. A Mac with more RAM will have more memory than a Windows PC with less RAM.
That said, it's a ton easier to replace hardware in a PC than a Mac.
Personally, I've always used Windows so I can't really give a good comparison for a Mac OS vs. a Windows OS.
