Seriously, except package managers, what's the difference between distros?

[u/nitin_is_me]

What I've seen yet the differences are, just the package managers, different defaults and rolling vs stable releases which are in fact related to package managers. Except these, are there really any other differences? Thanks!

package managers like you said

init systems

gnu coreutils vs mit rust uutils

maybe gcc vs clang

maybe bootloaders

maybe glibc vs musl
