is using bare metal server better or a VPS?

I just purchased a Dual X5150, 16GB, 500GB from delimiterVPS.

I have a small website and a forum which consumes less than 1GB of ram. Is it better to use some kind of virtualization on top of the server or use it directly? Any advantages of setting up Virtualization over a server? I heard restarts are much quicker when using openVZ, is that true?
