Mandriva or Mageia?

I've been putting this off long enough. I am a long time Mandriva user from the days of Mandrake. Not exclusive, of course. It's the distro I use at home and on my laptop at work. I promote it to novices and other Linux users alike. I think I use it because it appeals to the lazy part of me. I get things done with little or no hassle. No fireworks. Not too much bling. Not many surprises.
Ever since it was forked into Mageia, I realized that I would soon have to choose. But since there was nothing concrete from the fork, I waited. Then Mageia 1 came out. I waited some more. Now the new Mandriva is out. The updates are getting fewer and father in between for my  Mandriva 2010 Spring. Normally, it is that time when I turn on the backports repo and feed off that while I read the forums about possible show-stoppers. There wasn't much in the last few releases. So I think there shouldn't be much in the way.
I guess the real question is, how do I choose which one. I use Gnome on Mandriva, so there is that Gnome 3 choice also. After see-sawing back and forth I've decided to burn LiveCds of both to kick the tires a bit.  Only Mandriva doesn't have that anymore. And they only support KDE with a new tablet like interface.
The Mandriva upgrade instructions look frightening, largely because the English is confusing.

When you use --download-all option urpmi will download all the packages first and then begins to install all of them. It is strongly recommended option for migration to a new release with urpmi. It is used to provide reliable update, you need to download and update a lot of packages. If you do not use this option and during update process you face Internet connection problems, you will get a very bad situation when only part of system will be updated, that will result in problems with correct system working.

I'm having nightmares about my former Russian  math tutor repeating that to me again and again. Signs of influence from the Russian investors?
Not everything is going against Mandriva. There is no PLF in Mageia, so I'll need to figure out how that works out for me.
This is one of those times I want to shout out, " I HAVE A GREAT SYSTEM. I CUSTOMIZED IT AND IT WORKS FOR ME. WHY DO I HAVE TO KEEP REINSTALLING AND START OVER?" Especially with stuff like wine setups lying around, upgrades means re-configuring those again.
I find it funny complaining about change. Especially from someone who has probed monitor refresh rates  to configure X windows (Look it up kiddies. There is no more spectacular way to make your monitor into a paperweight).  Change is why I don't have to do that anymore. But I think we have reached a plateau. Hopefully my choices won't lead me to cliff at the end of that plateau.
