Of course, it always depends on what your particular needs are.
Chrome-Nice interface; Fast out of the box
IE-Nothing wrong with it: "security issues" are a joke-just get some free anti-virus protection: its slowness can be counteracted by how fast any new computer is.
However, I would definitely suggest Mozilla Firefox for the addons: https://addons.mozilla.org/en-US/firefox/
1. Themes: Change how Firefox looks-can make it look like chrome/IE, make firefox all glass, and many others
2. Usefulness: Including quicknotes, timers, stopwatches, time trackers, adblockers, flash blockers, video downloaders, etc.
3. Performance Boosters: This is the biggest reason I like Firefox. Even if you have no use for any different themes or useful addons, there are performance boosting addons as well. There is "Faster Firefox" (makes Firefox faster), "Memory Fox" (make Firefox use significantly less memory)
4. Customability: Though technically not an addon, there are also many sites that can be used to increase your browser speed (doubling for me). Here is the one I used: http://www.makeuseof.com/tag/the-ultimate-guide-to-speeding-up-firefox-3-5/
In conclusion, Firefox is the best if you are willing to spend the time to download some addons and change the configurations. Chrome is the fastest out of the box. And IE is just a nothing-wrong standard to fall back to if anything goes wrong with the others.
