Both together. Unless you just want a fast mag or two for scrims, then both. Battle belts are great for quick access, like a pistol, pistol mags, maybe a couple fast mags and a butt pack with a couple small items, but the don’t really have the real estate to load you out for a day.
Modern battle belts and plate carriers are lightweight and low profile. Together they create a well balanced poadout system and comfortable weight distribution.
Good examples
Battle belt: Ronin Senshi
Notice how short it is and how it’s design will stop it from shifting around on you. This thing can nearly tow a truck and can be used for anything from gun fighting to repelling. This is just one belt of this style. Grey Ghost and a few others make similar equipment.
Plate Carrier: First Spear STY
At just big enough to cover your vital organs, it provides a decent amount of real estate without making you too heavy. Laser cut molle, quick release straps and the ability to run hoses and cables internally. Optional pontoon system if you want to make it more breathable.
