Verdict
The heaviest annotator here — stamps, signatures, Office files converted on the way in — and the one built for people who mark up documents all day.
Best for
Teachers and reviewers going through stacks of submissions who need real annotation tools.
Dealbreaker
Twenty-seven of the last two hundred reviews report crashes, and thirteen more say Google Drive syncing stopped working. That is a lot of risk to carry a day's marking in.
The facts.
