I encourage my students and academic advisees to pay attention to how their instructors introduce themselves on the first day of class and use honorifics accordingly. I also tell them when in doubt go with the more formal/higher ranking option (Prof. or Dr.).

For me personally, I introduce myself to students as "Dr. Moorberg", but am not opposed to "Colby" or "Moorberg. I do get annoyed by "Mr. Moorberg" though. I prefer either formal or informal, and using Mr. just seems like a lazy attempt at formality. I acknowledge I have the luxury of assuming someone using Mr. is likely not because they are trying to dismiss my qualifications, which brings me back to my recommendations above.
