I'd say that the primary difference between the two in my mind is probably just the baseline amount of how much they'd view him as an equal partner.
Gebura knew him since their days as Kali and Daniel, when they were at their most human. She dislikes being vulnerable with most people, but she managed to open up to Daniel somewhat. I think that despite putting her guard back up for several reasons, Gebura wishes to have that same kind of vulnerability feel safe for her again with Chesed.
If we're talking in bed, I think Gebura likes them more on equal ground. If Chesed takes initiative once she's more comfortable, she's not unhappy at the thought of letting him have a little more control of the situation.

For Binah, I think she sees Chesed in less of a way of equals. She finds him interesting, in the same way a lepidopterologist would find a butterfly interesting. She wants to dissect him, and know what makes him tick. Pin him down against a corkboard and spread his wings so that she can observe how the scales align. She doesn't want to break him, but won't mind doing so as long as it satisfies her curiosity about him.
In bed, I could see a lot more dominance. She wants to see him down to his base desires. How far he'll go to please her to get what he needs. To see him Wanting her heel to grind down on him as much as she pleases.
