I can completely see where he's coming from. As a work truck I think it's the best one you've got. That Doka is nice, but not as nice as the black one!
The 660 has a few bars. I generally used to cut firewood with the 16" mounted in my bench. Less teeth to sort out if/when I hit something hard in the wood! I cut up a lot of sawn timber that I get off of sites - roof joists etc. I can be pretty sure I'll hit a nail at least once a day, although this carbide tipped blade doesn't seem too bothered by them so far. Even the old plate saw blade was fairly robust compared to a chainsaw.
