Major points:
There are no benefits to using one vs. the other, they both have their
role in web design. They can and should be used in conjunction with
each other to serve your interest best.
There are specific uses for both however.
ID's are unique, there can only be a single instance of an id per
page. Meaning every id on the page has to be unique. Whereas classes
are reusable as many times as you want on the page.
ID's have a higher specificty in CSS than does a class. ID's should
be used to identify unique areas or things on your page, whereas
classes define a set of things that all have the same style.
