It's significantly better. Basically, Microsoft added the tracking protection features[1] Firefox and legacy Edge have to Chrome. Yeah, in terms of sending data to Google vs. Microsoft, that footprint is similar, but third party tracking differences are huge. Edge sends a fraction of the requests to third party services while web browsing as Chrome does.
Google has decided to implement third party cookie blocking in Chrome recently... solely in incognito mode[2]. Firefox, Edge, Safari, etc. all do it all the time in normal mode too. This renders Chrome the least privacy-minded browser, primarily because Google heavily values ad tracking as a business practice.
