THE VERDICT

Firebase FCM wins on price and reach. OneSignal wins on features and ease.

FCM is Google's free push transport, unlimited and reliable, but bare-bones: no segmentation UI, journeys, or delivery webhooks. OneSignal builds a full engagement layer on top, advanced segmentation, in-app, journeys, A/B testing, geofencing, and dashboards, with a generous free tier and paid plans from ~$9/mo. Pick FCM if you want free, code-level control; OneSignal if you want marketing features without building them.
