Security teams are already mandating chrome as the browser, it's in a local maximum of controllable-enough + usable-enough... a disruptor in this space would need a really compelling value proposition.
I'd say Edge is more popular, especially in the shops that go all in on Microsoft/Office 365. It integrates better with the whole ecosystem, you have more control over it with policies, sync is easier, and most importantly, underneath is all just Chromium.
