Questions... is it better to pressure test from the radiator cap or the coolant reservoir cap?
Logic tells me that either side will work, but is there a preferred methods and why?
Thanks!

Good question. Do both hold pressure? I can't remember.
The Stant tester tests both the system and the cap(s). So, I suggest first test the radiator caps to see what pressure they release at. Then, if you find the cap releases pressure at, say, 15 lb., then pressure test the system at 2-3 lb. higher.
By watching the needle (how fast it drops), you'll also see if you have a big or small leak.
