went from Firefox to Vivaldi, never looked back for many years
on Android phone tried many, most recently was using Kiwi Browser, then for some time Firefox until they fucked up UI, so moved to Cromite, though my phone broke (never buy Google Pixel again, first broken phone after 15 years with smartphones and various brands including very low budget), so now I am on my old phone which for some reason doesn't support Cromite, so I am back at Firefox temporarily
Why not Vivaldi on android as well, and benefit from sync etc? That's what I've been doing for about 8 months now. Generally quite happy.
no extensions, cant live without uBlock Origin and few others
