>If you've only ever used this type of debugging, you should really try out a real IDE debugger once.

It's the opposite, I learned to program with java for android so a full IDE was my first experience. As I moved to node and then go and ruby I just gradually used it less and less as I generally 'debug' creating tests to check/reproduce behavior.

I do think I should improve my debugging, but mostly in terms of profiling. I very rarely feel the need to see a codepath run line by line.

I'm not saying my system is better or worse to be clear, I've just naturally gravitated to not using the debugger - I couldn't tell you why.
