That's old, old news. CDG has been greatly revamped. AF has much better lounges, especially if your LAX flight leaves from the M gates. And CDG has MUCH shorter walks. Bring track shoes if you go to AMS. CDG also has much better shopping if you are interested in that.
AMS is in the middle of more improvements, but no changes to the huge distances between gates and from many gates to immigration.
