AppDynamics commonly sold through enterprise agreements with multi-year commitments; New Relic is self-serve friendly.
If you're already in a Cisco enterprise agreement, AppDynamics is low-friction. Otherwise, New Relic is more approachable.

New Relic uses standard distributed tracing with NRQL for ad-hoc analysis.

Both support 15+ languages with language-specific agents.

AppDynamics has deep Java/JVM diagnostics; New Relic is more balanced across languages.

Pricing

AppDynamics: enterprise pricing — commonly $2,000–$20,000/month per environment with multi-year contracts. Not transparent on the website.
