Chrome vs. Edge is not a browser war, they are both Chrome.
Speaking more broadly, the browser war is all but decided until the Chromes fail of their own accords.
The only non-Chrome browsers still in existence today are Safari and the Firefoxes (Firefox and its various forks). Safari is only relevant in iOS by way of Apple gatekeeping, and Firefox hasn't been relevant for well over the past decade thanks to Mozilla's utter mismanagement and malice.
