I guess it depends on what you want it for. We all have our prejudices and for me, I don’t like a magazine hanging down under. In the Marine Corps I used the BAR and M14, great guns, loved that BAR except on a long hike, but that mag had a way of getting in the way. On an AR type I don’t like anything more than a 10 rounder, my boys like 30’s. I have an 8 round tube on my Beretta, front heavy to be sure, a box mag may balance better but for me, they get in the way, to each his own
