Flatpaks tend to work more reliably than AUR packages. For example, I tried the markdown editor apostrophe, which only works well with certain versions of GTK. Only worked reliably as a flatpak for me. Flatpaks sidestep dependency hell.
Flatpaks really shine on LTS distros, allowing you to run cutting edge versions of software on a stable older base system.
Most of what is distributed on flatpack is also available in the AUR if not packaged directly by the distro

I like that flatpak runs the apps in a sandbox.
