I would not call myself enough of an expert to make a comparison between the 2 companies. What I can say is my avatar with its 408 has a Champion Cooling Systems 22" radiator and is driven here in Florida without much drama (dual Maradyne/Jegs electric fan assembly). They were great to deal with and stood behind their product without hesitation when shipping damaged the 1st one I got. Let's put it this way...whenever I need another radiator, I'll be calling them for it.
