I switch between Chrome and Firefox on a tri-monthly basis. As a web designer/developer, it's difficult to express my hatred for Internet Explorer.
You can tell the worth of a web browser by whether you need a conditional stylesheet for your website to support it. I have never once needed to make a separate stylesheet for a website to work in Firefox, Chrome, or Safari. I have, however, written many ie6.css, ie7.css, ie8.css, and yes, ie9.css files.
Simply put, IE is notoriously bad at supporting the internet. That's why so many cloud applications are phasing out support for IE6 and IE7. IE has never been good at supporting web standards, and it's still vastly clunkier and slower than its competitors.
