Talking from my own experience I think Leora is really good at pulling in new subscribers, she seems to always be aware of showing enough on free cams to get viewers without subscription wanting more.
Leora was one of the reasons I got a subscription, and since I got my sub I have barely watched her at all, once I realized it's just teasing and "shows".
Masha on the other hand may not draw in as many new subs but keeps people already subscribed keep it up since you enjoy watching, as you said, showing her real life.
