Depending on how much Security and privacy you are looking for, Firefox, or Brave are the better choices. However, if you like Chrome, but hate the ads, then use this global adblocker,

As for all the other choices, worst are Opera & Dolphin, because they are Owned by Chinese Co.,and I believe a few others on the list are too.
Firefox is the only browser that allows hardening through extensions and gives access to internal browser settings. A light choice for those with little storage would be Firefox Focus.
Actually I use several versions of Firefox, Brave, Naked Browser, and Chrome just for certain things. If you want to remove ads from chrome, use this global adblocker:

I can't believe folks here at MT use Opera & Dolphin. XDA Developers has a big thread in forums about Dolphin. I suggest reading it. As for Opera, it was sold to some of the worst tech companies in China, who have been routinely cited for violating privacy. Any browser, security app, file manager by Chinese developers are a YUGE risk! Because they ask for nearly every permission available, have full access to data, and can easily add code later on. And I can't stress this enough, DON'T USE ANY Cheetah Mobile Products!!!
