They all run about the same honestly. I have dozens of PMAGS and Lancers and they are great. Have about 30 aluminum mags and haven't had a problem with them either. All told I have about 75 AR mags and couldn't tell you who made a bunch of them and don't worry about it either. I buy the ones that are a good deal and stock up on them.
Can't go wrong with the Lancers or PMAGS in my opinion.
