I guess it's because Rion has this unique aura that other big boobs girls don't have. For exemple, S1 have Saki Okuda, but she isn't even close to Rion when it comes to beauty. I didn't watch Sakura Miura yet, but she isn't as famous as Rion and it's too early. Nana Fukada also started this year but again, not even close to Rion. Just another big boobs girl with a "meh" body.
Bashing Rion for being lazy in her movies (it seems to be a trend) but writing about Nana "excellent performance", while I found her boring or random at best (I watch a bit of her E-Body movies and only one full video, her VR scene). Rion is doing about Julia did, what people call "vanilla movies" and it worked for her after all those years (it makes me laugh when I read "vanilla", sure she isn't doing a gokkun with 100 people but most people who watch AV are probably not looking for that kind of content).
Sure, I'm a Rion fan (her big boobs aside, she's lovely and everytime she smiles, it's nosebleed time) but I don't think she has competition in S1 or even in JAV in general. Most of girls with big boobs are kinda fat, not in a good shape or not pretty (Kaho Shibuya, Yuri Oshikawa, Hitomi, ...). Shouko Takahashi is probably the only one (I'm a fan) but she hasn't the same personality in her movies, she's more like a girl next door (the way she speaks, etc..)
