A big factor for me is how they interact. It is hard to explain but I'll try to describe it. This is mostly true for online play btw.

Some subs just execute orders and don't give feedbacks. The conversation basically becomes a succession of orders and tasks interrupted by yes sir here and there. It is obviously very frustrating. There is no point in a live session for me anymore.
Other subs manage to describe what is going simultaneously and make me feel more like I'm present. That's definitely going to determine if I enjoyed playing with you.

Honestly a lot of subs who belong to the first category if I play with them still it is because they have a big toy collection and I can give more elaborate tasks. Otherwise I feel no pleasure from it.
