Sallos or Zepar and why?

[Bizarre]

Whats the difference in how different “love” demons work?

I was wondering, what’s the difference in how Sitri, Sallos, Dantalion, Zepar, Lilith, Gremory, ect work or reach their goals? I see to be interested in all of them but yet I don’t know how they differ in work / personality styles. Any insight?
