On the Europa, not really! It has been handy in setting A/C level,
where you're remote from the tool while shimming something up - listen
for the beep, but hardly a big time saver. I will still admit to
having many other electronic gadgets at maybe $25 per moderately
worthwhile use. :-)

I don't really know, but practically -- in equalizing wing incidence,
the book says +/- .05, but .05 is an error at the wing leading edge
equal to less than 4 sheets of copier paper. It will be no more
accurate than what is ultimately being referenced, the mean chord line
at the root, and further assumes equal twist in the wings further out,
and exactly equal flap rigging.

What only counts here is at what angle an electronic level reliably
flips from 0 to .1 deg, or first hash mark on the Zircon, .07 deg. for
both maybe? The difference then with a bubble level is that it takes
a sharp eye to see less than .1 degree but possible.
