I was using Timescale for a small project of mine and eventually switched to Clickhouse. While there was a 2-4x disk space reduction, the major benefits have operational (updates & backups). The documentation is much better since Timescale's mixes their cloud product documentation in, really muddying the water.

Despite that, man it is really nice to be able to join your non-timeseries data in your queries (perhaps the fdw will allow this for clickhouse? I need to look into that). If you don't have to deal with the operations side too much and performance isn't a problem, Timescale is really nice.
