The verdict
The deciding factor is where you need the work to happen. Pick Segment when a shared customer data pipeline, destination routing, or identity-resolved profiles are the priority; budget separately for its customer data platform capabilities rather than assuming they come with Connections. Pick Amplitude when your team needs to explore funnels and retention, watch session replays, and run experiments in the same platform. The vendors also publish different usage measures, so compare costs against your own tracked users and event volume.
