I'm not a professional web developer, but in the experience I've had building a couple of JS heavy sites, I've actually found the Edge developer tools to be the best. If there's one thing microsoft knows how to do well, it's build developer tools.
This is probably very subjective, but I can absolutely not relate to that.
I certainly see where GP is coming from, Microsoft do have an awesome legacy in dev tooling that lives on to this day with products like VSCode, but browser tooling might be the glaring exception to this - perhaps since Microsoft never really was or became an 'internet' company.
I think that's a debatable assertion.
