Typically, that is the default file system. That is how you will get the best support when there is an issue. It will also be the most stable with your OS because the developers focus on that FS. So personally, I would use whatever is the default FS for whatever OS you decide to use.
To get off topic a bit, IMHO that OS should be Debian because it is just too awesome and Debian based OS's have the largest community. Also, it should be running on Linode.com ;)
