Welcome to A.S.!
Lots of opinions. Depends how you use your saws. As noted:
- 'Full-chisel' chain cuts faster, but can dull faster. I consider it like high performance tires on a sports car;
- 'Semi-chisel' chain cuts a little slower, but keeps cutting longer. I consider it tone the 'all-season radial' that is best for most cars, all around;
- Modern low-kickback chains work fine for firewood cutting on bars up to 24"or so. They don't carry chips as well on longer bars *if fully buried in the log*. You an bore cut with them, they are just a little slower at it.
As suggested, a semi-chisel, low-kick back chain that is properly sharpened will kick the butt of a full-chisel chain that is not.
I usually suggest that people buy a couple of different kinds of chains, and compare them themselves, side-by-side, on their saw, in their wood, doing the type of cutting that they do.
Note that you will be limited in the types of chains available at a home center. For more variety you will have to visit a full service saw dealer, or a catalog vendor like Bailey's.
