Compare the evidence for the same workload
Audit evidence and access
Ask each option's operator for a redacted request-log and export sample, its access model, and the configuration that produced them.
Use the audit-trail evidence checklistDeployment and operations
Name who patches, monitors, handles incidents, approves support access, and controls network egress and encryption keys.
Use the deployment-boundary questionsModels, cost, and exit
Compare a dated written quote, the actual allowed model set, usage limits, and an export/exit exercise for the same workload. Do not assume that a historic plan or feature is currently available.

Bring your evidence questions to a technical review.
Ask for the proposed configuration and a dated written scope before making a purchasing decision.
