Open a few news web pages, and run Discord, Slack, VS Code, etc, and you'll quickly run out of RAM.
It is noticeably faster, but Chrome is the new Internet Explorer in more ways than one, and many web pages don't work in WebKit browsers.
I use Safari as my main browser, I open Chrome only when I encounter a web site that doesn’t work in Safari. It happens maybe once or twice per year, and half of the time, it turns out that it doesn’t work in Chrome either.
That's exactly the opposite of my perception—for instance, it's been used to render help/support databases on my Mac for at least twenty years.
But, webkit is much better than chrome in memory usage. If only we could force slack and vs code to use the engine better suited for the job.
On the PC/Linux side I keep an old thermally-constrained i5 Sony Vaio ultrabook with a lowly 4 GB from 2015 around for the same reason.
The main dev box is a Ryzen 9950X3D/128 GB monster, so it's a bit of a difference :)
