Use the same brief and ask both tools to revise it against three explicit constraints.
Keep your input, instructions and required deliverable consistent.
Record errors, omissions and the time spent making each output usable.
Check whether the result exports into your actual working environment.
Compare the current plan and data terms required for that task.
Make your own call
Choose the workflow that meets your acceptance criteria with an acceptable amount of review. A tool can be a good fit for one task and a poor fit for another. We have not run a controlled product test for this comparison; these are source-based editorial starting points.
