Atolboo what are the pros against Mageia?
The margin of Pclos over Mageia is very small.
There KDE implementation is slightly better.
And there implementation of the Control Center also.
Flash is installed by default and google-earth and picasa-3.9.0 can be installed through Synaptic.
Packages in the repo are packed with better support/details.
You can install the latest VB with the 'Get Oracle VM Virtualbox' script and it does also installs the extension pack automatically with it.
Kdenlive automatically comes with the XVid4 .avi rendering option.
Of course there will there will be exceptions with respect to packages.
There reaction to problems here
compared to Mageia here
There is still a problem with automatic resolution detection of my HP LP2475w
As that can be set manually, it's not a show stopper.
SolusOs: I miss KDE there and is still very young.
Chakra: My experience is that it's rather unstable with there packages and still very young.
Sabayon Linux: Uses Gentoo testing and how stable is that.
But I never get PCLinuxOS Live CD running. Every time it stops at the moment searching USB (something).
It is the only Distro where I get this. So never get the change to test it.
I never got that problem and you can also test there reaction to your problem.
