Datadog's value is correlation. A latency spike on a dashboard, the traces behind it, and the logs from the affected hosts are one or two clicks apart, which is the difference between a ten minute incident and an hour.

Sentry is the tool most teams install first and remove last. An unhandled exception arrives with a stack trace, the release that introduced it, the users affected, and the breadcrumbs leading up to it.
Grafana is the visualisation layer that sits above other systems rather than a monitoring stack of its own. It queries Prometheus, Loki, PostgreSQL, ClickHouse, and dozens of other sources, and puts them on the same dashboard.

New Relic was the application performance monitoring product for a generation of web applications, and its repricing to per-user plus per-gigabyte was an explicit attempt to answer the complaint about host based billing.
GlitchTip accepts events from the official Sentry SDKs, which means adopting it is a DSN change rather than an instrumentation project. Stack traces, breadcrumbs, releases, and issue grouping all work as expected.
