Apple

Brave with uBlock Origin, AdGuard AdBlocker and Bitwarden.

I'm using Safari
It looks good, feels fast (although I haven't done much comparison). But tab-groups connected to focus mode really seals the deal for me.
The one thing I do wish for is more extensions, but most of the key ones I need are fortunately available.

Firefox for work related stuff. Safari for personal browsing/logging into services (run credentials through keychain).

As others have said, Firefox & Ublock for the win!

I find myself using Brave for most things currently but I do still use Firefox. I usually end up switching my primary between the two every couple of months.

Firefox works very well on my Mac. That's the one I use

Arc! No plans of going back!

Tried Arc. Was fun for 6 months as different but just went back to Safari as it at least just works.

Arc is wonderful once it 'clicks', but may feel slightly weird at first. I've been using it everyday since I got the invite (switched from FF).

I use Safari for personal browsing and Chrome for work (internal corporate stuff)

Firefox. Adblocking options aren't that good in Safari, Chrome is soon to ruin adblockers, and I trust Mozilla's intentions more than I do Brave's.

Firefox is awesome now, you should try it!

Brave and Safari

I used to be a Firefox fanboy. But they don't care for resources and just eat ram and cpu for lunch. So, it is not usable for me, unless I close all tabs all the time - which I don't like.

Currently alternating between LibreWolf and Brave. I tried Safari when I first got my Mac but it sucks.

Safari and Firefox. I use Brave on my iPad, but I'm trying to keep my Chromium bases browsing down.

All Safari for me. Keeps iPhone, iPad and Mac experience the same and syncs everything perfectly.

Mostly Brave. I LOVE it's adblocking and overall privacy. I'd probably just use Safari if it blocked as well though.

Safari for regular use and Brave for anonymous / testing stuff (science)

80% Firefox nightly 10% Chrome and 10% Ferdium

Tried Arc for a while, really enjoyed it but right now I'm using Edge (just as a test of the MacOS version). Used Orion in the past and liked it but I'm waiting for some updates before I commit to it full time (extension API still being worked on, no auto updates for extensions, etc). I've basically used them all at one point or another.

Brave for web browsing, Safari for video streaming. As far as I know, Edge on Windows and Safari on Mac will stream in the best quality possible due to DRM/codecs. Supposedly Safari uses less battery streaming video on Mac too.

I am heavily into the Apple ecosystem. My whole life is on Apple’s platform. So, I use Safari. I do though, have Arc, Vivaldi, Edge, and Chrome installed.

I have an old Mac (RMBP 2014) and I really want to like Safari, but the fact that it feels slower than Chrome and that I don't have an iPhone anymore really makes it more difficult.

Mostly Brave for daily browsing. But for work, I use Microsoft Edge.

Add me to the Arc group. Absolutely the best and most game changing app I’ve used in years.

Firefox but currently exploring Orion + Kagi search to see if I am going to switch. Heard about Kagi on kbin and it seems awesome so far.

I use Firefox with uBlock Origin. Not as nice on the battery as Safari or Brave, but I've always liked and preferred Firefox.

Currently using Vivaldi

Safari — mostly for the password manager, sms short codes auto entry, and privacy oriented features

Edge for work, Firefox for personal. Safari for fun sometimes when I’m bored.

Safari for anything personal (for easy sync with my other devices), and Edge for work stuff. Safari meets all my basic needs in a browser, and iCloud Keychain has been great.

Firefox on my personal machine and chrome on my work machine.

I primarily use Linux nowadays, but when I go back to my M1 Macbook Pro, I tend to use Safari. For me it's all about battery life. I'd love to use Firefox, but the battery drain compared to Safari is very noticeable.

I use Firefox because it lets me use Tampermonkey, and because I also use a Windows PC for gaming.

Vivaldi for most things, hardened Firefox for private browsing, tor for sensitive searches

Firefox on Linux machines at home. Mostly Chrome for work on the MacBook because the employer uses Google for everything.

I use Arc and Firefox. Arc is fun and daring, so I'm curious where it goes. I especially like their Spaces, which makes it simple to separate different contexts (e.g. work, personal, entertainment). Not only by cache and cookies, but also visually.

Chrome for personal use, Brave for work. I used to use Firefox but I need tab groups and I'd prefer a native solution for that. Simple Tab Groups seems unstable.

DuckDuckGo for Mac.

Safari (with Wipr), and for work Firefox (with ublock origin) because of compartmentalization and because MS Teams works (in Safari you need to disable cross-site tracking which I don't want to).

I use Brave.

However, sometimes the privacy settings are so good that certain sites don't function as well, especially if there is a pop-up element on a site.
