Give Firefox Developer Edition a try, if haven't already, and are looking for more robust development tools.
I'd rather not have my professional work tools be built against a beta channel when there are better alternatives.
I find different browsers excel at different things in regards to the developer experience. As an example I appreciate that Firefox had a formatted JSON view without requiring an extension. However Chrome also has capabilities that I wish were included in Firefox.
New features also land quicker, as it is built against Firefox beta.
