The big advantage is that I don't have to route power and ground all
over the place. You do have to think about each design and decide if
it's worth the extra effort. But then, you can do two-layer boards
this way, by taping two SS boards together, if you have a hard time
lining up the mask for etching.

And it's not that much more work. I panelize the two sides onto one
print, so I only have two panels to etch (inners and outers), and
doing two isn't much more work than doing one. The blind vias are
easier to solder-blob than the regular vias are to through-wire.

The thinner clad is a LOT easier to cut, too.
