Boxes take considerably longer to give you things you care about (grenades, gadgets) and are very static. They're better for supports intending to bunker down with a mortar or lay down suppressing fire. If you run pouches you can keep moving after you get your initial ammo tick. Honestly, the pouches are way better this time than they were in BF4.

Health pouches are OP imo you can try to pick off a medic from yards away but all he has to do is drop a pouch and sprint to cover. It's annoying at times
