The "Real Value" kit will help greatly in heat rejection; the rotors will run cooler, the new fluid will raise the boiling point, the SS lines and cad plating will keep things cleaner and nicer... but it won't change the front to rear brake balance.
"Best" is a set of four calipers and the hardware that both balances braking capacity and rejects heat at least as fast as you can generate it.
"Cost efficient" (to me, anyway) is a balanced set of four calipers that avoids mistakes like flat-spotted front tires, encourages greater confidence in street applications, and can tolerate occasional higher temperature track/spirited use, at a moderate price.
Maybe we need a Street Brake-Off contest. Rules: ballast to equal weight (maybe front to rear weight also,) same tires, and (for now) I would let pads be an open choice. Must be done on one day, same place. Best two or three decels averaged out of five runs. Have to decide about 100-0 distance or maybe highest "g" reading.
