I do a lot of web development.
Chrome is better than Firefox in many ways, though both have very similar abilities. Better, in this instance, is usually faster .. but I find it's also more responsive overall and less of a memory hog. This does change depending on what plugins you use, but a prime example is the firebug plugin for firefox. In Chrome, that **** is built in and doesn't suffer plugin-itus.
All in all, Chrome is my go-to browser. Unless I need to use firefox, and there are times when I do, but that's usually a site-specific thing.
