I’ve been trying to find a good tool to create drum-specific sheet music on my Mac, and have largely been frustrated. Expensive tools that do it all like Finale and Sibelius are just too heavyweight, both require lots of of tweaks to work well for drums, and felt a bit clumsy to me just because of their level of complexity. MuseScore looked great but the editing workflow just frustrated me, trying to get multiple voices in one stave (required when you have to chart up to 4 notes at a time in one place, because drummers have 4 limbs ;)) was far too fiddly and resulted in many annoying round-trips.
I’ve always been a fan of staying flexible as regards to platform, but it’s especially true these days, since my desktop environment is heterogeneous - I still tend to use Windows most for work, but for personal use I’m most comfy in Mac OS X now. I do have Ubuntu around too although I generally only use it when I have to on the desktop (although I love it to death as a server OS since it takes everything that is great about Debian and updates it a bit).
