My opinion is that none of those actually matters. The "one" single reason Chrome won market share was the same playbook how Google Search Engine Started.
Speed.
I watched hundreds of users, given the choice, or doing so themselves installing / using Chrome by their own selection. It was faster. The user experience was far better.
You could advertise the heck out of your product, but if it wasn't any good it wouldn't matter. For nearly 10 years Google Chrome was undoubtedly the fastest browser on the planet. It wasn't until Quantum landed on Firefox before you could at least have a few metric of performance wins going to Mozilla, and that is also partly because Chrome has slowed down a lot in recent years.
