Amazingly easy to get started. "It just works" and is reliable for the long-haul. The community (mostly on Slack) is easily one of the most friendly, responsive, active, and knowleagable I've run into among open source tools. The number of taps and targets is astounding and growing rapidly. Configuring a brand new tap/target that already exists usually only takes a few minutes. You spend longer getting your credentials than you spend setting up your plugin for the first time. That is also a statement on just how incredibly easy Meltano makes it to create a new tap from scratch. I've built numerous taps with their SDK and some of them I was able to build them in less than a day. Because it's a code-based tool, collaboration among multiple engineers is way more effective than GUI-based competitors. However, even though it's code-based, you actually don't need "real" coding skills unless your are going to create a brand new tap/target. It's mostly yaml templating and cli commands with some docker/cloud knowledge be useful if you are going to roll your own custom deployment. I love open source and I think of Meltano as a company/community that is doing open source right. They play well with a lot of other open source tools (Dagster, Airflow, dbt, Great Expectations, Superset, etc.)
