I use Opera. And before that I used Firefox. And I would say that yes, Firefox is better than IE. Although I do admit that I might not have the best reseach material available. The IE they use at school is an old sucky one that has absolutely no support for even the most basic interface improvements that Firefox has had for years, such as tabs.
With Microsoft finally realizing that it has to actually occasionally update IE, issues with security are decreasing. Most cases of works-only-with-spesific-browser can be worked around. So you just have to pick a browser that looks nice and has an intuitive interface and doesn't spontaneously crash.
