I dont really have a ranking because Maimy is currently the only one doing consistent GF experience NSFW ASMR, but here are some that have scratched my itch over the years (even if they fell off). Definitely your first three:
Maimy
Aftyn
its_bunnii
Jelzy
HeatheredEffect
Mood
Puffin
LunaRexx
CorneliustheCat
Rose
Tingletown
Wokies
Bella
They all have pretty good NSFW ASMR somewhere in their history. Not so much GF experience/cosplay stuff though.
People sleeping on sloansmoansHey, who here remembers Maple? Man, I wished upon a star that she would ever do NSFW or even just show her full face. That half a face she had was super fuckin hot. Oh well. I will just have to break into CERN to search for the alternate universe that she and Frivvy do OF with Fairy Char. Who wants to form a team like mission impossible...
