My experience is that Chromium DevTools are much more polished than Firefox's. For instance, the network tab is a pain to use with FF on a small screen because the columns have a large default width, so the Method column ("GET") is as large as the URL path column. And you can't resize them. Chromium has a better default, and I can resize them. If I view the detail of a request, pressing Esc will close the details view in Chromium, while it will toggle the console in FF. Even with the mouse, at first I struggled to find how to close the details with FF (the toggling icon is not part of the toggled window, it's next to the filter field!).
