One of the big draws for me was the CABS. On that size, I don't need a choil, really.
I already had a BAD, so the Choil less CABS really called to me.
That said, I really want a Boss Street for a more robust piece too! Not that I really ever abuse my smaller knives, but you could if you wanted to.
The SCABS will already have a perfect edge for slicing! The shop did a fantastic job on the edges! That is another selling factor.
The standard Boss Street is going to have a much more "robust" edge.
I always convex mine anyway, but not having to do it, and having such a pretty factory edge (perfect really) was such a selling point!
Really, it will come down to what your intended use is.
If you need to punch holes in floors, Dry Wall, wood, car doors, pry apart stuff, go for the standard version.
If you will do more knife appropriate tasks, get the thinner slicer.
But remember, if you carry the thicker one, it will still cut, and be much stronger. You can always improve the edge and make a pretty good slicer out of it (within reason).
You can't make the SCABS any thicker!
But for me, I tend to go thinner with the smaller ones.
