You're pretty much down to which apple tastes better. You'll find proponents on both sides and few negatives with either head. I do know that both fly very well at higher speeds, and both leave good holes in critters. I'd have to lean toward the Slick Tricks due to their consistency of manufacturing tolerances being a tad better than Muzzy's, however. In a dozen Slick Tricks you'll find maybe 1 that need to be on different shafts to spin and shoot well; the Muzzy's may have 2 or 3. That's about the only difference that I've found. Also, the steel in the Slick Trick seems to hold a super sharp edge a bit better than the Muzzy does.
