WP SlimStat vs. ExtraWatch Pro

I am looking for a plugin that can allow me to monitor traffic on my WordPress-based site (no readers comments allowed YET).

Ideally, I would be able to see in real-time the IP address of the current site visitors, but that’s not a must. The more important feature is the ability to analyze traffic by country, OS (including mobile), and browser type.

So far I found two great candidates:

1. WP SlimStat https://www.ads-software.com/extend/plugins/wp-slimstat
2. ExtraWatch https://www.codegravity.com/projects/joomlawatch

Can you share your experience with either (or both) of these?

Thanks.
