which would you choose? radiator
I run a Champion 26" 3 row radiator, a GMB high volume water pump, standard flow 180* thermostat, and a dual electric fan set up out of a 1995-2000 model year Ford Contour. Works great for cooling my ~400hp, .060" over, iron headed 340. I've sat in traffic when it's over 105* outside, still maintains ~210*. Most of the time it runs between 195* and 200* because thats where I have the fans set to keep it.
The issues I've seen with people running 3 core radiators have almost exclusively been caused by not having enough fan cfm. You need to move about 3,500 cfm to stay reliably cool. Less than that starts to depend on the conditions and your engine build. The Contour fans will pull 3,500 cfm on the low speed, and ~5,000 cfm on the high speed.
More expensive doesn't always mean better, the Dorman reproduction of the Contour fan set up is about $130 from Summit, and it outflows electric fans costing 2-3x as much. I think between the radiator, fans, digital controller, relays and wiring I have still don't have more than about $500 into the whole set up.
