I prefer virtualenv + pip. I primarily develop on Fedora which ships both Python 2.7 and Python 3.6. pip and virtualenv are built into python3, no need to install anything. Additionally, these tools + tox are commonly used for python testing in popular python projects [0]. I have found other colleagues that use other tools struggle with pip and virtualenv, and it puts them at a disadvantage when it comes to working with the larger python software community IMO.
