I've carried both. I see pros & cons with both, as well. Corrections tried another company's foam product. It sucked. No more foam. Inside a facility or on the street. The cone seemed to take effect quicker than the stream, but inside you were up close, and didn't have to worry about wind. The stream was pinpoint and affected less area, but aim had to be spot-on. Most of my buyers now, are younger gals. College students, joggers, grocery getters. Far different than the confines of a building. Thoughts>?
