Sierra and Decagon sit in the high-intent customer experience agent category. Both should be evaluated as customer-facing support infrastructure, not just chatbots: channel coverage, escalation controls, brand policy, action permissions, and quality visibility matter more than demo polish.

A serious Sierra vs Decagon evaluation should start with the same support workflow, same system-of-record permissions, same escalation policy, and the same customer sentiment checks. Ask each vendor how agent traces, supervisor actions, voice behavior, business-system actions, and fallback to human support are audited before launch.
