Helicone vs LangWatch

Our take

Pick Helicone if teams who will change one baseURL and then live in the request table. Pick LangWatch if agent teams who will pay a core seat and send events from production. Skip Helicone if orgs that already standardized on LangSmith and will not move the proxy (LangSmith). Skip LangWatch if teams that only want a $0 request proxy (Helicone).
