I think for the vast majority of cases it is better to use whatever you're most comfortable with. Some people just don't have the endurance to learn gdb or lldb, or they are allergic to Visual Studio on Windows because of how big and slow it is. They just use print statements instead. Some people have learned a few workflows with a debugger of their choice and for them it is easy to fire up a debugger.

However, for some things like debugging Windows kernel trickery it is impossible to use print statements.

Personally I like debuggers.
