If you are teams choosing a transactional API
Judged purely as an API. What the request contract guarantees on retry, how complete the webhook event coverage is, whether suppressions are readable and writable programmatically, and how much the message log retains when something needs debugging in production.
The order above is the general editorial ranking. Re-sorted against idempotency keys, webhook coverage, and event stream, the shortlist for high-frequency programmatic sends where a missed delivery is a product failure becomes Inbound (inbound.new), ParseForce, and Postmark. That differs from the headline order, which weighs all audiences together.
