I've used both print and proper debuggers plenty. I tend to lean on print debugging more these days. The thing about debuggers, in addition to often being a headache to set up, it usually seems tricky and time-consuming to get it to step to the lines you actually want to examine and skip the stuff you don't. And if you step past something but then later realize it was important, time to start over.

It's often faster and easier to set things up to run test cases fast and drop some prints around. Then if there's too much unimportant stuff or something else you want to check on, just switch around the prints and run it again.
