Output Tubes: Matching for Plate Current / Transconductance

I'm using a push-pull amp and attempting to match up 6550 output tubes from my stash. I understand that both Plate Current and Transconductance are important, but finding tubes that match up with both those values is rather difficult. Question: which of those two values is more important in finding a match?
