Windows or Mac?

Windows... I think because I've always used it, so I prefer it, but from what I've seen from the mac, I think I still prefer windows = D

i personally use windows but i think Mac is always better as better application compatibility and support from application developer

Mac looks sleeker but I prefer Windows because of program compatibility.

Windows is the best thing out there because it's the most widespread OS. If you're looking at doing just about anything then it's the best.
For security, Linux is a good choice, but no OS is completely safe.
If you're looking into giving up a lot of compatibility and things for a "good-looking" OS, then look into OSX.
