I do sometimes use print debugging despite having (in my opinion), a decent knowledge of the debuggers in the toolchains I use. Part of is that you could set a conditional breakpoint for a condition, if you know what it is, but sometimes you're just probing to see what differs from expectations, and putting every expectation into a conditional breakpoint is a pain with most debugger UIs. In theory you could use logpoints instead of print statements, but again the UI for this is often a pain compared to just typing in print. And even when you get to the breakpoint, you'll run into the dreaded "this variable has been optimised away" increasingly in modern languages, and it also doesn't give you a history of how it got there - maybe if rewind debugging was more commonly supported that would help, but it isn't. Also suspending a thread to peek around is more likely to hide timing bugs than the extra time spent doing IO to print.
