I personally as an end user can not tell the difference. I have both installed and use firefox almost all the time for home usage. For work I use chrome. Day to day usage is nearly identical. There are a few bits here and there on some pages where someone did something chrome specific. But that is rarely an issue. If I switched it out either way on all of my families computers I doubt they would notice. Never once have I got a call from a family member saying "I need browser X". For dev usage chrome is slightly better, but that is just an opinion. Even that is not that big of deal anymore as many people are just using transpilers and their JS is some sort of mangled form out of that. Also they should peal off a few bucks and donate to Mozilla or Mozilla will always be bound to google.
