I do like Samsung Internet, as well as Microsoft Edge and Opera (not mini and certainly not touch).
For me the most important feature is to be able to synchronize favorites (and other data if possible) between devices and to be able to read clearly any web sites.
So I switch quite often but I keep going back to Opera as it's the one for me that features a really good synch engine for favorites (and other things, but not passwords unfortunately, but with a password manager who cares now) and it also allow text reflow and this is the only one browser that I know that stille do this (text reflow is useful for sites that are not mobile compliant so there is large chunk of tiny text and you must scroll in every directions to read it, if you zoom into this text with opera : it will automatically reflow the text to adjust the width of the phone. This way it's super easy to read)
Edge was good but unfortunately it stopped syncing favorites between my devices and nothing I attempted to correct this has failed (anyway when it was working it was slow for something to be pushed from one device to another, with opera it's instantly in sync)
Samsung Internet, the only thing that bothers me is that sync is not done automatically (I must go into the browser extension to push the favorites on the PC to the Samsung clould...)
