I've been using the TAG Vanguard for executing search warrants. It's pretty basic in design and has a built-in three pouch with shock cord on the front flap which secures the cummerbund. Berry compliant and seems as well made as the plate carrier issued by the Marine Corps. I've never had my hands on the JPC, First Spear, or SKD rigs to compare it to.
