--help doesn't do anything functional so that's not a good example.

-R, --group-directories first are some notable, frequent options I use on GNU ls that are missing from MacOS ls. Along with every "long" option, which I like to prefer in scripts to make them more self documenting.

exa actually does support both, so in a way it's more compatible with my usage of (GNU) ls than (MacOS) ls is.

-R does work on macOS. It's part of POSIX and macOS is actually certified Unix.
