I wanted to support and use Plausible, mainly for the drill-down feature, which Fathom doesn't have yet.

But, I had two main concerns about this product from my trial:

1) Slow response time (~300ms) of the script when using a custom domain.

2) I liked its simple design and features, but looks like it's already starting to bloat up with trivial things like UTM tracking.

Some small UI bugs (like time range buttons not working) also need ironing out.

Waiting for Cloudflare Web Analytics to compare.
