What sort of complexity do you need? I've used them on my previous job and am implementing it on the current one. I have never heard of the last three you mention. Otel collector is very useful for gathering multiple different sources, eg I am at a big corporation and we both have department level Grafana stack (Prometheus Loki etc) and we need to also send the data to Dynatrace. With otel collector these things are a minor configuration away. For Kafka if you mean tracing through Kafka messages previously we did it by propagating it in message headers. Done at a shared team level library the effort was minimal.
