PCLinux OS comes with a lot of tools installed even in the MiniMe version.
Bleachbit is one of them.
It had this no nonsense feel and it is easy to handle and just works.
The look and feel of the desktop is better than with Mageia - maybe because of those pleasant sounds. PCLOS is probably the distro that a Windows user - trying linux for the first time - would prefer.
And that is a compliment. I can find nothing to pinpoint that does not work. It simply is a great desktop.
So this is a contest between PCLOS and Mageia. I will leave Rosa out of it (some would disagree with that) and Mandriva is non existent at the moment.
Mageia has those pleasant sounds too but not quite as good as PCLOS. The PCLOS menu does not look as good as Mageias - I do not know why they chose those fonts.
But the overall look and feel of PCLOS is better. This is a matter of taste so you be the judge:

PCLOS uses Apt-get where mageia uses urpmi. This is of no importance to a newbie and both have decent "software centers" to install programs with.
Mageias software center is more userfriendly than PCLOS with Synaptic for a newbie IMHO
But if you pick the full PCLOS version you will get pretty much everything out of the box.
PCLOS feels a bit "snappier".
PCLOS has been around for 10 years Mageia has been around for 3 years. But that does not have to mean anything.
The one thing that makes the difference is the rolling release.
To be able to tell a newbie that dreads the install - that he never has to do it again.
That is manna from heaven for him (and me too

) It means more up-time it means more and longer usability.
So PCLOS is a good desktop distro for everyone and especially for new Linux users.
For experienced Linux users the remastering capabilities are tempting. After you have put all the important goodies in there you can make a new "distro" and share with the world - easily:
Install
draklive-install and then
That basically creates your new distro.

What version did I test?
It does not matter - its a rolling release so I updated it and tested the
latest version.
Here is the "HW" I tested it on:
