Edge used to be unique,but then they just copied chromium.... It had much smaller scrolling which was great on touch screens. Now I have no reason to use it.

opera also used to maintain their own browser engine if i remembered correctly, but they all just dipped

Opera is also Chinese Spyware...

Proof?

Opera is owned by a Chinese company, and China companys need to suck their governments balls wich is common knowledge. Also its all chromium Anyway. Use Firefox.
