Reviewed verdict
Direct substitute — Most teams run one of these, not both.
Both are bought to push warehouse data into operational/marketing tools via reverse ETL, so most teams would standardize on one rather than run both long term.
Drafted by an AI model and checked by hand.
Switching takes real work. A judgement, not computed from the capability data.
