Not a fan of AppImages myself. For an universal format it has surprising amount of issues with different distros, in my experience. And the whole Windows style “go to a website, download the AppImage, if you want to update it, go to the web page again and download it again” is one thing I wanted to get away from. At least they don’t come with install wizards, that clicking through menus thing was a pain.
For one off stuff I run once and never need again, AppImage is alright. But not being built-in with sandboxing, repos, all that stuff, it just seems like a step back.
