Well, what criteria do you use to determine the "best"? Speed, complete-ness of search (if using proprietary engine), fewest bugs, best layout, etc? So, after some thought, here's my list. I do not, and have never liked Google at all, though I use two of its products.
Microsoft Edge
Google Chrome (yes, have to admit it, from periodic trials--performance and search engine are tops)
Opera--current default
Vivaldi
Moz Firefox
