Just spend a little more and go for a provider with a faster network, $100 for a server like that one is extremely cheap and it is logical it will perform much worse because most likely the network is oversold.

CentOS is a form of Linux, so is Debian. Linux is again based on Unix, real Unix does not really exist anymore in its original form. CentOS or Debian? I can tell you which one is best, but first you must tell me which car is best, which song is best and which color is best. It's just an opinion.

Oh by the way, the dedicated server with 3 drives will outperform the VPS any day once you start using PHP and MySQL. Try a benchmark test, if it takes you dedicated server to crunch a fully loaded Wordpress site in lets say 1 second, and deliver it over the network in 800ms, it is still faster than your VPS which would be chewing it for lets say 3 seconds, and deliver it in 500ms.
