Native browsers (Safari/Edge)- tend to try their best to grant a good user experience all around for the device you bought, so they should never be discarded. Pretty safe for people to just stick to these as a result.
Firefox- user focused on customization, privacy, features (Send to Device, RSS toolbar feeds, etc).
Chrome- focused on Google's best interests. No real privacy guarantee since that's in their profit incentive. Mostly a marketing backed browser, shiny Google adverts on Google services insisting Chrome is what you want.
I tend to recommend native browsers or Firefox, if the user has the inclination towards being a power user. I really can't see a purpose to Chrome, and it's hard to separate truth from fiction because there's a massive boatload of corporate Google fanboys out there that promote everything they create.
I'm more of the anti-profit incentive type, and prefer people simply do what they want to. It's worth considering if no one would build Google Chrome without a for-profit incentive (and it's highly unlikely it would exist without Google existing), then how could it possibly improve things for the better? It doesn't, it serves Google's best interests. Everything that does, are temporarily mutually aligned interests.
Most people don't see this for what it is, and think Google is their friend.
