Concrete advantages, I'm not sure there are any, unless it'd be its relative simplicity. It's my preferred Linux-based OS, and has been for 18 years (I also ran Ubuntu for a few years for a desktop, but went back to Slack). I really like that it adheres to the principles behind it, and it's super nice that it doesn't change between releases, so it always feels right at home, if it's a brand spankin' new release. And the combination of many official packages plus SBo means it's about as useful as other distributions.
