I don't feel strongly, either use `python` and it fails by default sometimes, or `python3` and fails by default sometimes. My personal opinion on how it _should be_; that distros provide `python` symlink to whichever sub version of Python 3.x (or even Python 2.x if olde-timey/LTS) that is ther "default" version, but alas `virtualenv` and friends exist for a reason.
