I prefer atomic operations whenever possible, so I'd rather than the whole
setq would fail. This catches the error earlier, and leaves the environment in
a condition that makes it easier to reproduce that error (it's possible that
some of the variable settings might change the code path such that the setq is
no longer performed).
