For a heavily laden 100, such as mine, and if 18" wheels are not a deal breaker (apologies to the OP as you stated 16")...then IMO Stoptech BBK rules.
Next best performing brake system (sorry my experience with OEM brake rotors, pads and mountain passes doesn't move the same meter's needle...), ART rotors + Porterfield carbon/kevlar pads was a distant 2nd place finish.
For the utmost in brake performance, peak power, modulation, pedal travel, pedal feel, etc., the Stoptech BBK system is a game changer; again on a heavily laden 100.
