Mostly Oregon Vanguard and Dolmar 496, a couple Oregon LGX and Dolmar 099 - these four models are my most favorite.
I also have some Stihl RS and RM, Stihl Rapid Duro3 & Picco Duro3 one each, Carlton A2LM, Oregon .404" round tooth, TriLink chisel & semi chisel (worst chains ever
), one Archer loop, and a couple no name loops.
I mostly buck skidded hardwood logs, turkey oak (being my neighbor, You may know it as "cer"), regular oak, beech, hornbeam, occasionally fresh locust.
Even though the firewood logs I tend to process are skidded, I prefer full complement round filed full chisel Oregon/Dolmar chains.
I have and tried semi chisel and round tooth, they just feel slow to me, which in turn makes the bucking experience boring (to me using chainsaws is all about having fun, I hate bucking logs when it turns into work).
Does semi chisel and round tooth hold its edge longer?
No!
Can One make more straight bucking cuts trough dirt embedded logs with them?
Yes, but they'll be slow and You'll be basically just torturing Your saw, bar and chain.
If You are good at getting Your chains sharp, go full chisel and pick a quality brand chain.
If are not good at sharpening Your own chains You may want to try semi chisel.
If Your wood tends to be embedded in sand and dirt (NOT gravel, stones), You might wanna consider giving Stihl Rapid Duro3 a try. It is an expensive Solid-Carbide tipped semi chisel chain. I used mine countless hours for a whole year before it got so dull that I called it quits. One of the cons of Solid-Carbide tipped chains is that they have to be ground.
All the above is just my own experience and opinion.
Your mileage may vary so take it with a grain of salt.
Cheers
