I'm not sure if Yixuan is actually popular or 2.0 just has the advantage of a new version update but in gacha in general, hebes/young girls tend to be the most popular since they have the most varied and expressive personalities.
Hag characters for example pretty much just boil down to 3 archetypes, ara ara mommies, sensual teases, and tall, dark aloof and beautiful. Lolis and smaller girls are more loved but people in general don't seem to think they're worth spending money on.
