Bill Tindall, E.Tn.
Starrett SFB I suspect most don't know what this name stands for.
What blade is best depends on what it will be used for. If sawing expensive wood into veneer a carbide blade makes economic sense. The veneers these blades produce can be used without further surface refining, which is to say, no waste of the expensive wood. However, a blade costing 1/20 the price could prove a better choice for resawing inexpensive wood, or sawing where mechanically damaging the blade is a risk.
Fewer teeth results in faster and possible more accurate sawing. When gullets fill with dust the blade effectively looses set and wanders. Fewer teeth result in a more coarse surface.
No one answer to the question of what is best.
