There some dommes I personally think can be very powerful. It's all matter of taste and preference. Here are the ones I like:
1. Mistress Hypnotist: She just stared her new patreon. Long term conditioning, "homeworks", very interactive. She built real D/s dynamics… she actually tries to enslave you and make you addicted.
2. Beatrix Vale: Sometimes she gets too porny for my tastes, but her hypno is top quality in terms of writing, performance and post production.
3. Goddess Nautica: Unique voice and style. Sometimes she is a bit too derivative, but when she sticks with her style she is very good. One of the best if you like HFOs practice
4. Mommy Sammys: Her first files were amazing. Nowadays she is a bit hit or miss. She does leans towards role-play sometimes, and her did somewhat shy away from her "evil" persona that made her content so good to begin with. But when she stick to her guns she is sexy af.
5. Mia Croft: Maybe the best old school domme active today? Her voice is pure sex. And when she does pure hypno she the files are amazing
6. 丂卄乇ㄥㄥ乇 尺丨ᐯ乇尺丂: Real D/s dynamics, she understands submission and domination like few others. She will go the distance (even in one on one dynamics) to make you literally fall in love with her. Her voice is an acquired taste tho
7. Listen2Lisa: She is a bit weird. The post production is meh, and the file are very simple in structure and style. But the one on one interactions are powerful as fuck. Is all about personal training with her. And she is mad good at it
These are the best "real" dommes imo. Maybe I'm forgetting someone tho
