Browser Alternatives to Chrome

I’ve been a Chrome user all my life and have unfortunately gotten stuck for a long while because all of my services and devices ran over Google. With the increasing implementation of AI Overview and growing security concerns I really want to switch but I can’t seem to find a good alternative for my needs.

Most importantly, I need a browser that runs well enough on both Windows and Linux, as well as a browser that doesn’t constantly bombard me with AI generated content. Customisation and cross-device syncing is a nice add-on, but not as important to me.

I thought I’d ask before I end up trying out 20 different Browsers. All answers are appreciated, thanks in advance!
