Older CFR champ Destroyers vs. Newer Champ Destroyers

I have not thrown one of the newer champ destroyers with all of mine being the CFR type that Innova was pumping out a while ago and was wondering if there is any big difference. I have found that the CFR champ stuff in other molds is slightly different and at times better than when Innova starts pumping out the same disc in mass productions. What say you???
