z is so much more useful because it automatically learns which paths you use most often. There is no need to explicitly mark folders. It just works.

How does it differ from autojump?

I don't know autojump, but from a cursory look: z is written in pure shell, is a single file, no external dependencies. autojump requires python, thus likely has more features.

IMHO, just for jumping around directories, z is good enough.
