I'm split about 50/50 between pmags and metal mags with magpul followers. I choose what I'll use based on who I'm shooting with.
Folks will walk across hot coals to steal a Pmag off the ground. But I've seen people walk across a range to grab a far-off magazine and then toss it back down when they realize it's aluminum because "those don't work".
So when I'm shooting with strangers I always use metal mags.
