I prefer printf debugging. a) it works everywhere, even say when the bug is only reproducible in a remote CI, or in languages that don't have good IDE support. My printf skills are top notch thanks to using it everywhere. b) the printf stuff can stay around until the next compile. I can easily vary it, put it into VCS, share it with others, etc. For IDEs such features may exist, but again I'm locked into an IDE.

Sure, in some settings the source code is not available and you still want to debug. Then I use debuggers. But outside of that I prefer printf debugging.

Note that I'm not saying that people who prefer debuggers are wrong. They probably have their reasons, as I have. Everyone should be allowed to use the method they prefer the most.
