I remember reading that Chrome had worked on fixing a lot of that bloat (so did FF). But Safari was a breath of fresh air in how fast it worked and didn't seem to constantly kill my battery.
Yes it has the occasional quirks. But I do like that Apple focuses more on UX than just DevEx by trying to implement everything and the kitchen sink web standards.
As others have said, we definitely need alternative browsers and browser engines.
But at the end of the day, it's just mostly WebKit (and Blink derived from it) and Firefox, so it's not like there's all that much competition.
That said, as a frontend dev, I very very rarely run into real world issues between Safari and Chrome. More often it's Firefox/Gecko that lags behind, usually in some sort of graphics optimization (SVG and canvas stuff). Also some differences in WebGL and webgpu support, but those are niche enough that it's not a big deal yet.
