Coracle.social is the cleanest and most intuitive. Simple but not bland and loads threads amazingly with no awkward locks or having to click back. Afaik its just #[0] working on it. Very responsive and even tyoing this out on a ohone via web browser I can follow entirely what has been typed. It is the best hands down even if it is still (like all tbh) a work in progress. Also as you like light mode for day there is a simple toggle switch on the main screen lol.
