I personally liked IRyS>Kronii>Fauna>Bae>Mumei.
IRyS was the perfect length per segment and going by the standard 3D showcase was pretty good for her, Kronii was a different kind of good but some segments were a little too long, Fauna was good i don't have complains other than the ASMR segment, Bae's guest segment went on for way too long for me, and Mumei i just found boring save for the guests.
