I utterly dislike Zabbix (enough to login here and complain). I guess that if it fits your needs is all good and fine, but as someone that has been in charge of defining and feeding it with LLD rules and registering multi-dimension metrics with Zabbix Sender, I feel scarred by it.

I cannot find my way around the Zabbix web interface neither and most of the templates, rules and macros system confused me, deeply.

On the other hand we have a Prometheus + Grafana stack for another system and the model makes all the sense to me. I guess that there is something in time series and graph plotting that just clicks with me.

I've monitored two whole sites with Zabbix, dozens of servers at different companies, and everyone was very satisfied with it, myself included. Zabbix has extensive documentation, no one should be confused after reading the manual, all is explained there. I've fed it through zabbix_sender too, and while it can be a complicated setup, if you design it well it will seldomly need maintenance.
