I did watch a fair amount of JAV before I became a fan of the Muscats.
I remember seeing stuff by Muscats (e.g. Kasumi Risa), but didn't pay it much attention.
Some of the Muscats wouldn't have caught my eye for aesthetic reasons (Kishi, RIO, Rukawa, etc.),
because I like a bit more meat on the bone.
I did have favourite JAV actresses, I won't mention names because I doubt anyone here would have heard
of them (and they have retired).
I'm surprised Asami Yuma got past me (plenty of the right kind of meat on those bones

).
I love watching Kaho on Ebimasu, and Kasumi Radio; but her JAV stuff leaves me pretty cold.
I really like Yuria's Ebimasu and JAV.
Most of Nishino's JAV is OK...but watching her get 'up close and personal' with a lady friend SCHWIIIIING!

(especially if that lady friend in Ogawa Asami).
I like watching Minori's JAV (even better when she's with another Muscat - e.g. Asami Yuma).
Watching Rukawa Rina's JAV showed me a whole different side to her. Man, she can get 'nasty'/raunchy!

Often, on Ebimasu, she looks so 'butter wouldn't melt' innocent.
Yuma is, kind of, the same on Ebimasu and in her JAV performances. The same personality, I mean.
To be honest - and I hope I'm not offending anybody - Akiho's JAV doesn't do much for me.
I occasionally watch Haruna Hana's JAV , which is pretty good (but I wish they'd spice it up with a bit more variety genre-wise).
Her Ebimasu performance didn't impress me.
