Reviewed verdict
Direct substitute — Most teams run one of these, not both.
Both products are used by the same privacy/compliance buyer to run cookie/consent and related governance workflows, and running two systems of record for consent is rarely intentional.
Drafted by an AI model and checked by hand.
Switching is a project, not a swap. A judgement, not computed from the capability data.

Not offered means the evidence sweep read the vendor's documentation and did not find it — hover to see the page it checked. — means no verdict either way. Hover a recorded cell to read its evidence and source; a cell with no source says so, and each cell says whether an AI pass or a person set the grade.
