+1. Likewise, I am a big fan of MagPul PMAGs, either the deluxe windowed ones or the standard ones, both for regular use and for SHTF spares storage. With their polymer construction and array of features, they are clearly the future of AR magazines, and they are only a few bucks more per unit than good, basic USGI mags. They are consistent in quality of their manufacture, too.magpul pmags the only way to go!
Interesting video I found on youtube. Its a durability test of several of the mags you listed getting run over by a truck.From my "firearms tip & suggestions thread:
Avoid USA brand, Mec-Gar, or any bargain magazines of unknown origin. A reliable magazine is 50% part of keeping your AR malfunction-free!
