My only complaint on that rig is that I wish the med or radio pouch (it can be had either way) was on the right-hand side and the two mags on the left-hand side. But if we establish that we're going to either (a) probably not need a spare mag or (b) have an emergency mag on a belt or in a pocket or (c) have a Redimag on a "home defense" gun (my personal preference), then having the mags on the off-side probably don't matter.
I stumbled across that rig recently, and from a civy/homeowner/shoot-house standpoint it looks ideal to me.
If they had the pouches set up the way I would prefer them, and they would sell to non-badged folks, I'd spring for the $1k rig with the 3.5 lbs plates Level III Standalone and sell off my current Mayflower rig.
