I don't have a concrete data for all the radiators I've used, but here are few things I remember of...
Fluidyne - used it on my blk FD with Greddy FMIC. Worked pretty well, but w/ FMIC, still goes upto 90+C when boosting. When used with SMIC, no problem.
Koyo - I was one of those people who used it and had to get rid of it as fitment wasn't great (w/SMIC). I think I was using this with PFS IC/duct, and the intake
PWR - This was VERY similar to fluidyne. Fitment was good and construction was VERY much the same as others.
Mazdacomp - I currently have this on my MB FD. No problem and seems to be about the same as the fluidyne. construction is good and fitment wasn't a issue. Like Brent said, price on these are much higher but not sure the gain is worth the money.. if there is any.
Koyo, N-flow - I also picked up one of these and will be using it with my Blk FD. By theory, this seems to be the best. by extending the flow and using the larger capacity of coolant in the Koyo Rads, I'm hoping to run cooler with this.... instead of cooler, I should say this will help maintain more stable temperature. I know Chuck Westbrook used this in hot Houston weather and saw good results.
Also, there have been many debates about radiators.. in my opinion, I think stock rad does pretty good job. If you are worried about the plastic tanks, you could also go with brass replacements. But most bad stock radiators I've seen goes bad around the core instead of the tanks. I'm sure others have seen otherwise..
