I've used both, but I'm mostly a windows user simply because I'm more familiar with it. While Mac's don't have the security issues that Windows computers do, I tend to circumvent most of Window's security holes (especially those in Internet explorer) by using a different browser. Even after all of this, Apple tends to make the best computers, rated best in both reliability and customer service for desktops, as noted by Consumer Reports, for the last several years. As for laptops, they are also at the top in service, but reliability-wise it is a close second to Toshiba (quite a surprise, if you ask me).
So, closing word, getting one computer over another is entire your preference. As for why this topic is getting, well, off-topic, I don't know. And, if you really want to run an editor on a Mac, try these three options:
1) Get virtual PC and run a version of windows.
2) Learn C++ or another coding language, get the source code of the program you want, convert it so that it will run in a Mac environment, and recompile into a new program.
3) Get a cheap, used, windows PC, use it as an editor, and transfer files between the two.
