InfluxDB vs Prometheus

Hi all,

I’m pretty new to Home Assistant. I am looking for a way to have more control over graphs. Therefore I want to use Grafana.

What database option do you suggest?
InfluxDB or Prometheus?

If I’m not mistaken then Promotheus is a default package? But a lot of people seem to use InfluxDB. What is the best option? What are the pros and cons? I did some research and both seem to be similar…
