Same here. I come from a strong Postgres and Microsoft SQL Server background and I was able to get up to speed with it, ingesting real data from text files, in an afternoon. I was really impressed with the docs as well as the performance of the software.
Having a SQL like syntax where everything feels like a normal DB helps a lot I think. Of course, it works very differently behind the scenes but not having to learn a bunch of new things just to use a new data model is a good approach.
I get why some create new dialects and languages as that way there is less ambiguity and therefore harder to use incorrectly but I think ClickHouse made the right tradeoffs here.
