Patronum edges out Harmony Email and Collaboration on rating (5.0★ vs 4.8★), but the gap is small enough that pricing fit and feature differentiation should drive the decision more than the headline number.
Pricing entry tiers: Harmony Email and Collaboration at Free of charge trial, Patronum at Free of charge trial. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (seats, usage volume, integrations) varies.
