With prints, I'm usually not targeting one spot to see if it looks right, I'm putting them broadly over everything that gets hit to find where the data diverges from my expectations. Maybe I'll do another round to narrow it down some more, but it's only after finding the right place like that that I'd use the debugger, so I don't have to waste time stepping through everything.
