Some top comments:
“Snap is very Canonical centric, with one central repo, and a “works best on Ubuntu” feeling. Flatpak is more decentralized. Personally, I expect snap to die like all of the other things Canonical keeps inventing.”
user replied: also, snaps is dependent on systemd containers. so I hope it will die.
“Flatpak works the same across distros; Snap is only containerized in Ubuntu. Also, Snap always does some weird mounting thing for me. I’m not really sure what benefits Snap has over Flatpak.”
Note: These discussion does matter. A newbie doesn’t just remain a newbie when they use Linux. Sooner or Later. I hope u know this better than me.
