Yep, been using FreeBSD on the Desktop since 1996.
I've used Linux for plenty of things, but I tend not to unless I need something thats written specifically for Linux.
There's very little I need Linux itself for.
My issues with Linus were a few design decisions, how stuff gets into the kernel, how the distributions work, how things are poorly tested/etc.
Sadly now that FreeBSD is using ZoL I'm encountering a bunch of problems related to that :(
