I actually swapped over to Microsoft Edge. I have a 2011 Macbook Pro 15" 16GB ram and 2GHz i7.and it works really good.
It doesnt chew up battery, CPU or Ram. Havent had issues with some pages like Safari does.
Has solid features and its a browser made possible by the
Chromium open source project.
Chrome was very slow on my ageing machine but found less errors running some sites. Chrome would zap battery and heat the hardware up and before I knew it fans are running hard.
Safari was ok but load times were average and load site errors on some pages Been using Edge for 12 months and has been a good solid browser and I never thought I would say that.
