This is the kind of question more applicable to fora - you'll be getting a lot of radical posts :)
Anyway, I find Chrome slightly buggy, and in general that Firefox works much better than Chrome on Ubuntu, even speed-wise. And it is completely open-source, updates very often (next three versions all coming this year with loads of new features), and has all the add-ons you could possibly need. I myself was a Chrome-fan till a few months back, and, well, I'm not turning back. If you like Chrome's looks (like me), you can get all of them by using the right themes (Chrome-FX) and add-ons. You can even get downloads to open in a new tab, put downloads in the status bar, anything. It is also much more customizable, even if you don't use the about:config page.
One more thing I notice is that, on Ubuntu (but not Windows), having many add-ons slows Chrome down, but not Firefox.
