Some debuggers take longer(1-3 secs) to spin up than it takes me to add a print, compile and run and see my theory confirmed or not.

If I want a debugger and see e.g. the complete variable scope at a breakpoint, I'll use a debugger. If I just want a very quick sanity check I'll use a simple print.

Once you enter debugger land you're there. When I'm currently not in the debugger but rather compiling and executing "for real", it seems more straightforward to me to not enter debugger land when I really don't need it. Personal preference.

There are scenarios, where 2 print statements can tell you more quicker, than breakpoints. You have to step through the breakpoints, right? 2 print statements in different parts of the control flow can tell me everything I need to know at a single glance.
