Your top 3 things are very open ended and interpretive, so you have to define them more clearer.
My top 3 with each one defined for specificity:
1. DFK with passion like you mean it and throughout the session.
2. Passion (IOP) that is at least seemingly real (moaning, ego stroking during DATY and especially in CFS).
3. Not a provider that loves to suck dick, but one who loves to suck MY dick.
A provider who can do at least those 3 things BCD during the time I pay her for, will have my now and foreseeable future regular business.
