In my experience, Chrome is way better than Firebug or Firefox's builtin tools for development. Firefox's debugger doesn't appear to have any way to debug webworkers for example. You can't reformat source. They only just got SourceMap support and it doesn't appear to work as good. No syntax coloring. Poor profiling tools, can't get a timeline which shows frames per second, breakdown of paint/style recalc/layout/composite, no memory/heap profiling UI, etc. No explorer for local storage or filesystem apis, no manager for app-cache. Nothing like chrome://net-internals for analyzing network issues, and on and on.

I'm sure they'll fix all that in time, they have a good development team, but to say Firebug is clearly superior is obviously based on not having used the Chrome tools to do anything significant.
