From everything I've read all the aftermarket radiators have less fins/inch that the stock and thus offer decreased cooling capacity. Even the expensive Mishimotos. I push my cooling system to the limits all summer towing in 100F heat so I went with a stock replacement on my previous truck. Had to buy thru a local dealer as UPS destroys them.

If you aren't towing heavy in high heat the aftermarkets should be fine. Performance Radiator is a good option. They apparently supply the unit that Bulletproof Diesel sells for about 2x the price.
