Not that anyone asked either, but in terms of the best meets I've been a part of/the best V-Tubers I've met;
Top of the list has to go to Cottontail, Vexoria and probably Buff Pup? Just in terms of disarming anxiety and making the conversation feel like you're talking to another person. Cotton and Vex are (as you can guess) super fucking hot but they're not prudish hot, they're more notices you checking out the cleavage and makes a joke about writing the URL to their spicier sites hot. Buff's also a total bro that'll spark up with excitement the moment you mention your hobbies or ask for gym and workout advice.
Low end of the list has to go to most past and present VShojo members, excluding Zen on account of them never attending a meet and Mata for being new. But bottom of the list has to go to both Silvervale and Mouse. All for the same reason though, nothing like being stood around their booths and seeing them shift from monotone "Hey, yeah thanks for coming" to seeing someone with a camera on them and then pushing out all the energy they have to greet them.
