Looking for independent input, I find that this site
techradar.com/best/browser
says

1. Mozilla Firefox
(But: somewhat Slow & Memory Hog)

2. Microsoft Edge
(But: Fight for Default, Does Not Work on Older Computers)

3. Opera
(But: Not Fastest)

4. Google Chrome
(But: Resource Hungry)

5. Vivaldi
(But: Excessively Customizable, to the point of Distraction?)
