Both are conversational assistants. This is a task-based decision guide, not a scored benchmark.
For drafting and editing
Give both the same paragraph and ask them to preserve its facts while improving clarity. Compare omissions, tone and the changes needed before you would send the result.
For document work
Check supported formats and current upload limits in each product. Use a non-sensitive sample and ask questions whose answers you can verify in the source.
