How to decide which is the better browser for me: Google Chrome or Safari? Consider that it is often said that...


Safari is more battery/CPU efficient.
Most people will never run across a web site that runs better on Chrome than on Safari (excluding Google explicit sites).
Memory consumption is dramatically better with Safari vs Chrome
Excluding extensions that have security risks, Safari has a comparable list of available extensions.
Safari fares much better in terms of security. Google Chrome is comparable to user-installed malware.
Incredible developer tools like Instruments (just enable the "Develop" menu)


See Chrome loads very slowly while Safari very fast

Safari vs. Chrome for Mac: 10 Reasons You Shouldn’t Use Chrome (2016)

In light of that I do not understand why anyone would want to run Chrome instead of Safari.

But browsers change a lot and often.
Websites with old opinions do not.

How do I find out if these assertions are really true for my current setup?
I use Chrome for work related stuff with its list of bookmarks etc 

And Safari for personal stuff including banking

So if (and that is a big if) I let someone do a quick search on my machine at work then they are in chrome...

Nothing to do with memory use - and that is not an issue as my macbook pro is sufficiently powerful.
