dont have a single go-to for distributed tracing observability, but im a big fan of the open source tools.

ive been setting up observability for a few distributed systems lately and keep bouncing between Jaeger and Zipkin. Both seem to do the job, but Im curious about what others are using in production and why. Are there specific scenarios where one clearly wins over the other? Or maybe youve moved on to something else entirely? Looking for practical advice on what works well and what pitfalls to watch out for.
