I am not an expert on this subject.
A few years back I did do a good bit of research on the subject. I used a
similar block (Lee Block) instead of CB or poured concrete. The major reason
that I chose the blocks was water seepage. I became convinced that you
can't stop or even properly channelize underground water over a long period
of time. The blocks allow the water to flow through.
IMO the blocks have a much more natural look than a CB wall or even stucco.
This improves even more as they age and you get some natural variation.
The 1" per course step back softens the height of the wall a bit
If you do a little research I think you will find that stucco may fail
quickly when hydrostatic pressure is present.
