Verdict
Rosie (8.7/10) is best for solo owners who want 250 minutes for $49 and a dead-simple setup. The catch: calendar booking and call transfers start on the $149 Scale plan; the $49 plan texts a booking link instead.
Retell AI (8.4/10) is best for agencies and developers who build their own voice agents. The catch: you build everything yourself, from booking to transfers: it is a developer tool, not a ready-made receptionist.
