Need more stopping power

The size of the rotors that can be used are limited by the size of the wheels. That's a major reason, when you see some of these high performance sports cars, you'll notice they have very large rotors to increase their braking capability, AND they'll additionally have 20in+ size inner diameter wheels to be able to accommodate those larger rotors. The most common wheel size on our JK is a 17in wheel, so that's the limiting factor all these BBK's are working with.

The Rotor kits (dynatrac and teraflex) will re-use the stock calipers and stock pads, they just include larger rotors and brackets to move the stock calipers further out.
The front-only Big Brake kits (mopar and teraflex) will include larger rotors, new beefier calipers, brackets to move the calipers out, and then possibly some other items like brake lines, boosters, whatever, depending on kit. Apparently these use larger pads.

There are two different types of upgrades being talked about - both use stock sized pads.

Even though these have more powerful calipers, they use stock sized pads.

The size of the pad is limited by the size of the caliper. If the size of the caliper didn't change then an increase in pad size is not possible.

When the size of the caliper increases then the pad can increase with it.

Even though the ProGrip system seems minimalist compared to the others, and I was sceptical too at first, but are all those other parts needed when they do the same job? The reason I say that is that I have driven other JKs with both the Teraflex and Mopar setups, and there is no downgrade in stopping power with the simpler Dynatrac kit, and I actually liked the brake feel better wirh the ProGrip. Personal opinion, of course.
I have not tried the front-only caliper upgrades, so have no frame of reference for a comparison. It just makes sense to me that a bunch more clamping force up front, with the weaker stock system in back, would cause more nose dive. And a 4-corner upgrade should provide a more balanced feel.
The Mopar kit doesn't use the same size as stock pads.
