I like them all. At the moment I'm watching Kronii the most. She debuted as a "too cool for you" character, and she actually played it off really well for a while. But her interactions with literally anyone else has shown her to be a massive dork and borderline menhera. As she's calling it, "character development." Mumei is kind of going through the same thing but a little more intentional with the whole "I'm a cute retard but really an evil genius" shtick. Baelz and Sana are just fun to listen to, they bring energy and bantz. Fauna I've watched the least because I'm not into ASMR and her voice seems to be stuck in a soft, motherly deity mode, but seeing her trap Kronii and write gg was savage. I'm team unity.
