why not just go with Cent?
Being a personal laptop, with /home thoroughly backed up, I sometimes get impatient to try out the new features. :)
A meta distribution allows you to upgrade at your own pace. That is, following a stable branch of software or a more cutting edge path or mix and match?
Point is the choice is all yours. No upgrade paths like the aforementioned where just about every other upgrade realistically results in a re-installation of the OS.
Check out Gentoo and be done with the Windows-esque upgrade paths, also the pigeonholed approach where here it is and this is what you get.
Bottom line - freedom to choose.... an out-of-the-box formula or/and build it from scratch if you wish all with the same meta distribution.
