I agree that Chrome's dev tools are faster and crash less. I also find them more visually appealing. I wouldn't say they are better than Firebug, though... there are a few kinks they need to work out.

One of them is console.log():

  (function(){
	var obj = {};
	console.log(obj);
	obj.new_value = "hello";
	console.log(obj);
  })();

In Chrome, this logs an object {new_value: "hello"} twice, as opposed to the expected: an empty object, and then the aforementioned object.

It's not something I encounter often, but when I do, it's really obnoxious to have to work around it. I mean, it's console.log() ffs.
