I used both _extensively_ and 'worlds ahead' is an exaggeration. Pexpect makes perfect sense if you need expect semantics in Python without using a FFI Otherwise, I feel that a reason for favoring pexpect is because Python is not TCL and 'a lot of code' means using others' libraries for which you could not find TCL alternatives.
