I use it as much as possible. Its user experience on touch windows devices (Surface Go in this case) is several orders of magnitude better than Chrome and Firefox... is not a usable browser, performance-wise in my experience.
Edge is brand new, and foolishly branded to look like IE, this might stop average users who know about getting Chrome from using it. But it shouldn't. It's extremely rare that I'm forced to swap over to Chrome. Mostly I use Chrome to keep my invasive work IT staff from having access to my private browsing info.
