I'm currently using Firefox on all devices as my primary browser, but there is a single feature that I've gotten used to in Chrom* browsers on mobile - 'pull down to refresh' - that looks indispensable to me, and I'm planning to move to Brave on mobile just because of that (already replaced Chrome with Brave on Desktop as my secondary browser). Yes, there are add-ons to do that on mobile too, but they are all inconsistent and half-baked. Chrom*'s built-in pull to refresh is very smooth.
I primarily use Firefox on my desktop, but I use Brave on mobile. It seems somewhat easier on the battery than Chrome, which would make sense being as it's blocking content that can be CPU intensive.
You might like it, though. I've used Brave's mobile sync and it works for bookmarks across devices quite well. It's surprisingly simple to set up, too. I don't fret much about forgetting whether I opened a tab on my phone or desktop if I remember to bookmark it.
That said, I still use KDE connect to send links to my primary Firefox instance and vice-versa, but the bookmark sync is in some ways more convenient. I'd imagine they'll eventually synchronize more things, like tabs.
Try Kiwi Browser for Android. Its a Chromium-based browser with built-in ad-block. If you want, you can even install uBlock Origin or any other extensions as it natively supports extensions.
