Both are mature, full-stack observability suites covering metrics, traces, logs, and more. Datadog has the widest integration catalog and the slickest product surface, but its per-host plus per-feature pricing can balloon as you turn things on. New Relic consolidated onto a single platform with consumption pricing (data ingested + per-user), which is often cheaper for smaller teams and simpler to reason about. Choose on pricing model and integration needs, since feature parity is close.
Datadog
Broad observability platform with hundreds of integrations.
The capabilities overlap heavily; the real difference is the bill. Datadog charges per host and per product line, which rewards careful enablement and punishes "turn everything on." New Relic charges for data volume and seats. Model your own usage against both before committing.

You need a specific niche integration→DatadogDatadog has the largest catalog of turnkey integrations.
You have a small team and want predictable cost→New RelicConsumption + per-user pricing is easier to forecast at small scale.
You want the most polished dashboards and APM UX→DatadogDatadog is widely regarded as the most refined product surface.
Your spend is dominated by a few heavy hosts→DatadogPer-host can work in your favor when host count is low and dense.
You ingest huge log/telemetry volume→New RelicModel it carefully — data-volume pricing can favor either, but New Relic bundles more.
