Not used it, but ic seems to be compatible back to python 2.7 so not really comparable. I can't use the builtin thing in my python code because the host software for my plugins is running python 3.6 embedded and only recently upgraded from 3.3 in the latest release so if I want to maintain backwards compatibility I can never use the new python builtin. I expect lots of other people are in the same position.
