If you're looking to switch to something like Matomo, you might want to also consider the platform that I'm building: https://usertrack.net
The advantages over Matomo would be the much cheaper price for features similar to their premium ones and that the codebase and UI/UX is a lot more modern.
I am still adding new features and improving it, so any suggestions are greatly appreciated!
