I'd disagree as someone running grafana+influx+telegraf for a few reasons.

Dealing with 3 things... feels about as much work as zabbix. That one requires server + db + agents. Basically the same components I'm running.

Promql/flux - while I know it, I almost never use it - instead in grafana click the database name, metric name, aggregation and I'm done.

While you need people to use it effectively, it's the same for everything, including mysql for zabbix. You can dump prometheus/influx somewhere with no configuration and survive for quite a long time.
