What is the difference between \usepackage{mcode} and \usepackage{listings} for MATLAB codes?

I know there is available in the MATLAB Central File Exchange site the mcode.sty package, which allows to put MATLAB codes into TeX files.

However, there is also available in LaTeX a package called listings.sty, which I guess does pretty much the same thing.

What is the difference between them? Are there any advantages or disadvantages?

Thanks in advance.
