All legit mag pouches work fine as they are made to carry real weighted mags not plastic mags...full of plastic balls
Esstac are great for open/quick access/reliable retention.
Equal to HSGI, although TACOs can hold a variety of mags, and release with less of a tug, however Esstac can be easier to reinsert a mag due to them staying open - I mean TACOs close up some when empty.
I prefer Esstac and Tacos on a rig.
That said WAS pouches with bungee retention tops are super fast, have zero drag and less bulk.
With belts you don't want to have to pull the mag hard to release.
Hope you've got a Velcro inner / rigger outer belt combo, 4 mags on your hips is going to move around a lot otherwise!
PS I've got a ton of WAS Coyote pouches I need to shift.
