Linux has worked great for us for 10+ years in various flavors. My
apps are mainly computational Chemistry.

We've used CentOS. Great. No problems. Also toyed with Red Hat
Enterprise in the past. Good too but the packages tend to be older.
Some would argue that's the point so that one gets a stable system but
sometimes it is irritating. Also you need to pay for the Licenses.
I've had an OK experience with Fedora too. But some say this is too
"unstable" for mainline HPC usage.

Just my 2 cents.
