Personally, I prefer native packages (DEB, RPM) over other formats. My main reason is that the primary purpose of Snaps and Flatpaks is to deliver the latest software versions across all distributions with minimal effort from developers. Since I mainly use web browsers, which receive updates regardless of the package type, I find no additional advantage in using alternatives. The only exception for me is Bitwarden, which I use as an AppImage. However, other users' needs may vary, so I understand the value of using Snaps or Flatpaks.
