No, seriously, what is the best distro for web applications?
qhoxie: You should give us reasons why you have narrowed it down to those 3 and what you level of experience is.I personally use Gentoo or FreeBSD whenever I have a choice.  A significant reason for that is years of experience tuning these for my needs; it has become second nature.For some environments I have used CentOS with good success, but I still end up modifying and trimming things so it feels more like Gentoo.  In the end, you would likely be happy with CentOS, Debian, or Ubuntu as far as binary distros go.
