I read a report earlier this year which focused on browser security and if memory serves me correctly I think MS Edge scored around 98% whereas Chrome scored 97%. Sadly I can't find that report but I'm pretty sure it was done by the Which? magazine. Each browser was subjected to a number of known risky sites to see how the browser security responded, both were pretty much level pegging.
Correction!
Found said article, read it and make up your own mind. OK, so not which 'best browser' per say, but best and worst for phishing protection. Article starts part way down on this page:-
