For large GUI-based programs such as photo editing, drawing (Krita), 3D modeling (Blender), etc, there are 3 main ways to install them, each with pros and cons:

• using apt

  • Pros: integrates with system libraries, version is curated by Mint/Ubuntu maintainers and usually more stable

  • Cons: lags a few versions behind upstream, especially when the next Ubuntu LTS is nearing release it can be quite out-of-date

• download a deb or tar.gz release from the project’s website or GitHub

  • Pros: you get the latest version

  • Cons: does not update automatically

• using flatpak

  • Pros: has the latest version, solves some visual compatibility issues (Qt apps on GNOME for example)

  • Cons: takes more disk space because dependencies are duplicated, sandboxing can break some features

Personally I try to use apt first, unless the version is really old then I try the tar.gz install and finally flatpak. Which method you choose is up to you.
