I have very high hopes for Ladybird as it's being developed, but it's not really fair to call it Tier 1 when it's pre-alpha stage and not really suitable for general use yet...
Brave is definitely not a 'tier 1' browser in any world. Their whole existence had been mired in controversy after controversy[1], lots of these incidents involving privacy and general shady behavior.
Arc is kind of promising, but I never really tried it after discovering that it's the only browser I've ever seen that requires (!) you to have an account with them. The obvious next question is 'what for?'
