The short version

Only MQTT has a free tier, so it costs nothing to try first.
Each has a real cost: MQTT mQTT is an OASIS standard messaging protocol maintained by a standards committee, not sold by a vendor; there is no company-controlled price list, subscription, or edition to compare because implementations are independent open source or commercial products built on the spec; Ecobee installation requires a C-wire in most cases, necessitating professional installation for some users unfamiliar with HVAC wiring
They diverge on capability: MQTT covers Publish-Subscribe, Ecobee covers Room Sensors.
