> lack of a promise of full PromQL compatibility (too many PromQL dashboards built by too many teams)
This is a classical FUD. VictoriaMetrics is used as a drop-in replacement for Prometheus, Thanos and Mimir. It works perfectly across all the existing dashboards in Grafana, and across all the existing recording and alerting rules. I'm unaware of VictoriaMetrics users who hit PromQL compatibility issues during the migration from Prometheus, Thanos and Mimir to VictoriaMetrics. There are a few deliberate incompatibilities aimed towards improving user experience. See https://medium.com/@romanhavronenko/victoriametrics-promql-c...
> seeing features locked behind the Enterprise version (Mimir Enterprise had features added on top, not features locked away)
All the VictoriaMetrics features, which are useful across the majority of practical use cases, are included in open-source version. The main Enterprise feature - high-quality technical support by VictoriaMetrics engineers. Other Enterprise features are needed only for large enterprise companies.

I recommend reading real-world case studies from happy users, who migrated from other systems (including Prometheus, Thanos and Mimir) to VictoriaMetrics - https://docs.victoriametrics.com/victoriametrics/casestudies...
