A good chunk on picking package managers is there in Linux, except Snap and Flatpak. Snaps have their advantages and downfalls, and same with Flatpak. However, both Snap and Flatpak are multi-platform. Linux Mint is a derivative of Ubuntu, and used to also be known as the OS that grew while Ubuntu stagnates, oh how the turn tables. I use Ubuntu, and get access to both Snaps and Flatpaks. Linux Mint has Flatpak by default, while Ubuntu uses Snap by default. If it is picking on the question of if it supports Snap or Flatpak, Ubuntu supports both while Linux Mint is throwing a temper tantrum about Snap. If you need a generic package manager, the ones where the selection of distribution does matter, they both use APT, a DPKG frontend from Debian.
If you want a distribution growing, and not throwing a temper tantrum because they are... not liking something... Ubuntu would be the better option, but you will need to manually install Flatpak.
