Except that it is safer, in my mind. I use Firefox almost exclusively. All of those wizzbang features are Internet-Explorer-only features that have no place in the W3C XHTML (or HTML) standards, and frankly, they don't exactly improve my internet browsing experience. Most of the time, when I see all of those things, I think that I'm looking at a page made by an inexperienced web developer who wanted to put every piece of code he could find on the internet into his page. What most people would call a Script Kiddie.
On the other end, Internet Explorer doesn't support many features that are in the W3C XHTML standard that Firefox does. It has gotten much, much better with the release of IE7, in respect to CSS, but it still falls behind Firefox in several key places that make it terribly difficult to develop a useful, interesting, and interactive web page compatible with both browsers without going out of your way to program specifically for "Most Browsers" and "Internet Explorer".
Unfortunately, Internet Explorer still has the market cornered, though Firefox is gaining momentum. Personally, I ignore Internet Explorer all together when making my personal website. Unfortunately, I don't have such freedom when doing other people's.
