I like Chrome but lately I've spent almost all my time in Firefox Developer Edition. When I use Chrome it's to verify that it behaves the same way on more than one Javascript engine.
Chrome seems to have a tenancy to paper over some bugs and not report them back to the user (even in the console). It's the main reason none of our devs use Chrome for primary development anymore (it's not worth the extra dev time when QA fails on all other browsers) and it's just used during QA.
