You should try FreeBSD (2014)
I recently switched my personal box to FreeBSD. I honestly find it significantly easier to manage than Linux, and have greater trust in its reliability merely from its simplicity.<p>The single biggest thing which stood out for me was PF (from OpenBSD). Anybody who has ever had the grace of managing IPTables on Linux, give PF a go with /etc/pf.conf (docs: <a href="https://www.freebsd.org/doc/handbook/firewalls-pf.html" rel="nofollow">https://www.freebsd.org/doc/handbook/firewalls-pf.html</a>, my config: <a href="https://github.com/jamescun/infrastructure/blob/master/roles/common/files/pf.conf" rel="nofollow">https://github.com/jamescun/infrastructure/blob/master/roles...</a>).
