Let me enumerate. Printf survives debugger restarts, shows up in git diff, usually messes less with the timing, can be exchanged with coworkers or deployed to users and be toggled with logging rules, has the full power of the programming language, the output is easier to run "diff" on to compare runs, works in CI containers, has no problems with mixed language environments...

As far as I'm concerned, breakpoints and backtraces, especially of crashes, are the superpower of debuggers. Where they are not immediately applicable, I usually don't bother.
