I don't think the head really matters. There's a lot of really good heads out there.
What matters to me is how sharp I can get them, and how easy it is to get them sharp. (also durability but that goes without saying).
I'm apparently 3 blade sharpslexic. I could never get my woodsmans sharp. Even though a lot of people claim its easy. So those are sitting In a tackle box somewhere.
Zwickey's, grizzly's and Kodiaks are awesome heads for the money (plus lots of elbow grease). I find that they take a bit longer to get sharp due to the having to aggressively redo the grind angles. And out of a pack of 6, there's a good chance one or two has a blade that isn't straight or flat. On some of the zwickey deltas I got the edge was sort of concave in the middle. And on some of the grizzlys/Kodiaks the rear end of the blade was rounded off to the point where its impossible to fix without extreme metal removal....which I find very frustrating when attempting to sharpen on a KME. Also in my mind the widest part of the blade needs to do the most work. When its rounded back like that and harder to sharpen its also frustrating to my engineering mind. I like a nice flat/straight edge. At least that's my experience with those heads. (we seriously need to start a gofundme for these company's and get them a $50 jig to hold a consistent edge during grinding. Its not hard to make a flat edge. That would gain them some more business from me. I don't want to have to spend 10-20 minutes per head getting the edge straight).
I really like the KME sharpening system, so I choose heads that work well with that method of sharpening. I have to sharpen the heads for 3 hunters so the amount of time and effort to sharpen a head is important. My dad is worthless at sharpening and would shoot a dull head and not care (and I don't want to spend 4+ hours of my life tracking a deer that should've been dead within sight), he also carries them in a fairly inefficient hybrid back/side quiver that dulls the crap out of the heads very quickly due to the haphazard way he throws them in (he no longer gets grizzlys). And my bro is just getting into bowhunting again...although he is starting to become sharpening inclined, so I may get him setup with a KME. The point is I don't really like having to sit around camp late at night for hours resharpening my dads heads after he shoots them into the dirt or at a squirrel or just due to the quiver dulling them.
From what I've found the easiest heads to get sharp are the magnus stingers and zephyr's (which are out of business). I also really liked the old magnus 1's and 2's.
I think i've gotten those zephyrs sharper then anything else. And sasquatch's leave a mean hole. I know some people express concerns over their welds being weak. So my quiver this year will contain cutthroats (pending inspection), zephyr tempests (I think), zephyr sasquatchs, with maybe a zwickey delta or grizzly on standby for hoggy areas.
Anyway, that's my ramble if its worth anything.
