As with anything, it depends on what you want to do.

If you have an OLAP heavy workload with long scans, etc (which is the type of queries prominent on the ClickHouse page - e.g., Q0 is "SELECT COUNT(*) FROM hits;"), then I would highly recommend systems other than Timescale. (Although we are also working on this ;-) )

But if you have time-series workload, or even, if you love Postgres and are building a time-series and/or analytical application, then I would recommend TimescaleDB.

ClickHouse is great. I just believe in using the right tool for the right job. :-) There are many areas where column store engines beat TimescaleDB. But nothing comes for free - everything has a tradeoff.

Genuinely curious, aren't a lot of time-series workloads OLAP oriented?
