It works with most websites, it syncs my bookmarks across computers, lets me reuse my existing Google account instead of needing to make a new one, and I really don’t care about my data going to Google because I already give up my data in exchange for free services (which feels like a win-win).
Even if you don’t care about your data, there’s so many better options out there in terms of features and usability. The only benefit of Chrome over anything else is that you’re already using it.
