I’m a happy clam on Fedora Linux. Just got tired of the Microsoft tax. A lot more secure.
Fedora was my first Linux back in 2001, and when I switched, I went to CentOS, which is RedHat Enterprise without the support.
Always been a RedHat family fan. At work I tend a few hundred Ubuntu servers, and they're okay, but they feel just a little weird at times. :-)
The Ubuntu folks change things around just because they can. It breaks stuff left and right, every major release.
The RedHat family is stable, and I like that.
