This has been my experience as well: I only resort to the debugger when my other avenues have proven fruitless. They can also be useful for Heisenbugs. However, I did have one job working on an embedded device with no console at all, and a JTAG debugger was invaluable there. But I would have preferred to have a console and be able to do printf debugging, as for easier bugs it's just a lot quicker.
