This has been my experience with ClickHouse as well...that is, you can basically close your eyes while writing the schema and still maintain to get extremely impressive performance.
That being said, ClickHouse also has a ton of clever levers you can pull to squeeze out better performance and compression which aren't used by default, such as using Delta/DoubleDelta CODECs with LZ4/ZSTD compression, etc. Not to mention, MATERIALIZED VIEWs and/or the relatively newer feature MergeTree Projections[1]
