First, their technology is far beyond the humans. Humans designed the first Cylons, but after that they got quite advanced. And remember Cylons aren't afraid of dying (kinda sounds like the Muslim terrorists), since they know they'll just be put in another body. Well, they weren't afraid since we know now that they are beyond range for resurrection. That might change things for future interrogations.
I don't think that their tech is better than human tech, or they would not have needed #6's built in back door. In individual confrontations, humans seem to do pretty well, even with obsolescent tech like the Galactica.
