Apple

Oh boy, nobody likes this answer in my experience but… More than anything, I use Chrome everywhere.
It goes back to when I used Windows & Mac machines daily, and Chrome had the best bookmarks search and extension (uBlock, now origin, and tab suspender).
To be fair, for a handful of reason, I use all the browser regularly, but my primary is still Chrome on everything.

Few things I’ll add, that might make me switch to Safari:

1. Extensions have to be BETTER and better integrated. Trying to use: complete and custom ad block, session manager with/and tab suspender, 1Password. Currently it sucks.

2. iOS/iPadOS Safari needs to be better at: Tab Sync/access across devices. Mobile Chrome is way better at this and we all know that’s an advanced Safari wrapper.

3. Chrome and mobile chrome sleeps tabs better, AND has unlimited tabs, mobile Safari still does not - come on now. I understand people are different, but I want to organize and close tabs myself, not have them all closed when I reach a max.

Honestly I could go on about this- Chrome is somehow just better. I WANT to use Safari, because there’s things like 2-factor codes and extensions, that Apple locks out for other browsers, but every-time I use chrome I could frustrated by it.
