I would say option b, as unicode-math supports unicode characters inside
math mode. Maybe some users would prefer a latex source that
contains the unicode symbols  and not the corresponding macros.

Ot maybe a better solution would be to add a checkbox in
Document->Settings->Math Options and let the user decide
between option a and option b. but that would probably
require more work.
