4buyer types

Verdict by buyer type

regulated financial: Neither separates itself on published approval and audit detail. Microsoft Sentinel documents permissions and rule expiry but no approval gate or per-action record; Splunk SOAR (Cisco) states neither approval controls nor an audit trail on the pages read. Ask both for the control documentation in writing.
lean team: Microsoft Sentinel is easier to size up before a call: it publishes pay-as-you-go and commitment pricing, with playbook runs billed separately. Splunk SOAR (Cisco) offers a free trial with no credit card but no price list.
MSSP: Neither Microsoft Sentinel nor Splunk SOAR (Cisco) states MSSP terms on the pages read. Ask both for multitenant approval settings and per-client audit exports.
Microsoft estate: Only Microsoft Sentinel says anything specific: it is the Microsoft SIEM itself and takes Defender XDR incidents as triggers. Splunk SOAR (Cisco) states no Microsoft-specific detail on the pages read.

When to pick each

Pick Microsoft Sentinel when the record a reviewer reads after an action decides the purchase, because it lets a rule condition on who last updated an incident (user, playbook or automation rule), which gives change attribution but no per-action record on the page read.

Pick Splunk SOAR (Cisco) when connector count and breadth matter most, because it states 2,800+ automated actions and 300+ third-party tools, a tool count and an action count.
