The performance will be similar across most products since the limiting factor is the cell count of the converter. Most of them are 200 or 300 cell. That said, I suggest you focus primarily on construction quality. HFC's are heat cycled constantly and the welds need to stand up to that process. Plus, all of the parts should be properly welded and checked for fitment against a jig. If the HFC is poorly constructed, then it may cause fitment issues with your headers and exhaust. One area I suggest you pay particular attention to is if the flanges are flat or curved. An easy way to check is to place the flange against something flat (granite tile, non-wooden desk, etc.) and look at it from the side. No light should peek through and the HFC shouldn't rock on the flange.

My point? All of these products cost <$500, which is cheap for a worthwhile performance mod. Pick the nicest one and move on. I have Berk HFC's and couldn't be happier.
