I used brave on my Android after replacing Opera finding out that Brave does MUCH better job with adblocking. So I gave it a try also on my desktop (I didn’t know it existed on desktop)
As an Opera user the MAIN thing I miss and I find really amazing on that browser is the Sidebar. Its brilliant. Especially with messenger/instagram and now Whatsapp integration. I can tell you that I miss it and I still use Opera side-by-side with Brave for that reason.
I hope Brave will bring a feature like this.
