It's interesting that most people on Windows PCs switch to Chrome when Edge is the default. It was obvious why people switched from IE6 to Firefox and later from IE7 to Chrome; IE was terrible; Firefox was better; Chrome was better still. Edge is not obsolete, unstable, or a security nightmare the way IE was.
Chrome even has significant user share on Mac OS; the numbers I'm finding are around 40%.
It's hard to guess whether people are much less inclined to switch browsers on mobile than on desktop, or if they just like Chrome. Either way, the odds are against anyone who tries to compete with it.
