Homebrew is so good that I use it on Linux whenever possible.

Most Linux package managers cannot separate user-installed packages from system packages. This makes cleaning up your workstation nearly impossible and a pain in the ass, since you can't tell what should be removed, or more importantly, what can be removed.

Also, most native package managers update much slower than Homebrew, meaning you often only get outdated packages.

Isn't that what dependency detection does? Whenever I'm not sure if something can be removed, I just try to remove it, and if it would break something else, the package manager tells me. I can broaden my scope and see if that's also an unnecessary dependency for something and follow the chain, with it eventually ending up with a set of packages where I actually get the prompt to proceed or not (meaning nothing in it is a required dependency for anything remaining), or I see a package I definitely want to keep around and stop. If I'm interested in what's part of the base system, I just check the metapackage for the base system.

This doesn't sound like something that's a problem with package managers in general compared to maybe some distros just using them poorly.
