GetElementById complies with the W3C Level 1 DOM, while the forms[] array does not -- it's Level 0 DOM.  In general, the first is recommended unless you need compatibility with very old browsers.

But beyond that, both will give you a DOM object in return, and so are functionally similar.
LVL 15

Is it not just a different way of getting the same object?

document.forms is part of the DOM specification and so should not be unnecessarily avoided in favour of getElementById, simply use whatever is easiest.
