Daemons and Demons aren't the same thing, just to point that out. Daemons is actually a word used for Spirits in general, I think.
Some people work better with Demons, some people work better with Angels, most people who look into it far enough will find plenty of Demons and Angels that they can't work with at all as well as plenty of both that they can. It's more about personality chemistry then the history of the being you communicate with.
Xoros, assuming by "Daemon" you did mean "Spirit" then most people do, actually. Spirits tend to be more understanding of humans then either Angels or Demons since most Spirits have been human at one time or another. There are Angels and Demons that have been as well, but not as many as Spirits have been.
