Not to detract from your overall point, but has Microsoft really done anything innovative when it comes to Edge, aside from painting over the Chromium skin?
The only noticeable difference that I've observed is its integration with Bing.
They made it vastly better in terms of resource utilization, specifically RAM usage. Anytime I restart Chrome to update the browser it's astonishing how much RAM is freed up after all my tabs open up again. Edge seems to have plugged a lot of memory leaks in comparison.
