Exactly. At work for example I use the dev tools debugger all the time, but lldb for c++ only when running unit tests (because our server harness is too large and debug builds are too large and slow). I’ve never really used an IDE for python.

When using Xcode the debugger is right there and so it is in qt creator. I’ve tried making it work in vim many times and just gave up at some point.

The environment definitely is the main selector.
