Personal choice.
But, you can carry a lot of ammo on stripper clips in less space and weight than in mags. And you can load a mag with strippers in mere seconds. They work and have for nearly 50 years.
A bandolier holds 140 rounds on strippers. Nothing fragile about the setup. Soldiers have been dragging them around all over with no ill effect. That's typically how the ammo gets issued in the first place. Beyond 3-4 loaded mags, a bandolier is the way to carry extra ammo. I wouldn't want to carry another 7 20 rounder mags or 4 plus 30 rounders. Throw the bandolier over your shoulder and you hardly notice it's there.
