I decided to jot down some of my thoughts on after using it for a month.
@kev > For example, the Telegram desktop app as a Flatpak is 783MB, whereas the DEB is just 21MB. That’s a massive difference!
Flatpak uses shared runtimes which are huge. Graphical app stores often shows total download size as a size of application. This confuse a lot of people. As before any flatpak app is installed no runtime is insalled as well. The app store shows sizes of every app that big. But actually they are not.
@danny @kev it is less efficient then apt. Flatpak apps run completely independent from the system libs. A runtime is the base system of an app. But there are many runtimes and the most popular are three: GNOME, KDE (it is used for many Qt apps too) and Freedesktop runtimes. LibreOffice uses Freedesktop and Telegram uses KDE. For example, Firefox and LibreOffice run on the same Freedesktop runtime so the answer is yes for them.
