Replying to POC vs. Komperdell

I'm looking for a new backprotector (and all other vital parts). The second most important thing (right behind safety) is comfort. Does anyone have experience with the Airschock Vest from Komperdell or the  Torso Vest or Torso Armor Jacket from POC?

I'm looking for first or second hand experience, and not "I think this one looks cooler" info... I live in this shit ass flat country called Belgium, so there aren't any shops where I can go to find more information about these or try them out. I could wait till I'm in France to get these things but I would like to get my stuff together before I leave.
