Both have their pluses and minuses.

It was delightful when auditing the experiences from a potential new client in Firefox Dev Tools the other day, and realizing that I could see, inline to the target DOM element, JS events tied to them while looking through the source. Saved me a good amount of time.

When I'm looking for pure-play performance auditing, Lighthouse integrated into Chrome's Dev Tools are an obvious win.

So yeah, each have their strengths and weaknesses.
