I was waiting for someone to come out and say it. 6 months ago, I couldn't imagine using another browser regularly but chrome has become so slow for me, I can't stand it. I switched to Firefox.
Chrome was (probably still is) the only usable browser left on Windows, but I never used it or had to use it ever since I switched to Macs a few years ago. Aside from the plugins ecosystem (which I don't need) Safari works infinitely better (loads faster, uses less resources, even with 100s of tabs, and has nice little features like the Reading List, Reading Mode, Force-Touch Peek and so on) and fits into the OS X lo…
What I did notice after the last Safari release, was that because it's faster/smaller memory footprint, it also used less battery.
