correct way to install is flatpak most of the time
It's probably SUPER intimidating how many options there are for something as simple as "package management". Who to trust. etc. People are just rough, and unkind. Stick with what works for you. What your'e comfortable with. That's honestly the ONLY important aspect of this whole Linux endeavor. Complete control of YOUR computing experience. That gets lost in opinion and subjective conjecture more often than I can stand, honestly. It really is SO much saner on Arch, though. You're absolutely correct. That's why I stick with it myself. It gets out of my way and lets me do what I want to do.
Wow, so this is what it looks like when a country decides to stand up for it's people and protects our privacy. Neat.
