What is in your opinion a better open source alternative to prometheus?

Borgmon was inspiration for prometheus but was a totally different project so it is a complete rewrite

I feel like a broken record, but we are having great success with Victoria metrics as a drop in replacement.

Promscale looks interesting. Keep the architecture of Prometheus while storing the data in TimescaleDB and using SQL as the query language (together with the TimescaleDB-specific extensions to it). Does anyone actually like PromQL?
