>>32490265ch is faster-paced, but also fairly chaotic.
Part of the chaos is nip shitposting, but another part is the fact that Nijisanji has a much, MUCH bigger presence there. Compare overall thread numbers between Nijisanji and Hololive over there. There's an unironic nijinigger presence there.
2chan is slower, but is better moderated and has images (5ch is text only, but has previews for linked images). From the last cultural exchange thread (Some anons made a thread here and there was basically questions asked here, answered on their thread), they just want a place to talk about holos in peace without the chaos of 5ch/other forums
