I've just been using conda environments lately. How much am I missing by not using virtualenv instead?
Why did you take up conda in the first place ? venv and pip are part of the python project and conda seems to be yet another package manager in the already crowded and shady space of npm, brew, ports apt yum etc. I've always been puzzled at how they managed to shoehorn themselves into the python ecosystem while offering no distinct value as far as I can see.
They provide useful packages that aren't (easily) available via pip. For example, numpy with MKL or Tensorflow GPU builds that don't require/presuppose CPU support for new vector instructions. Moreover, their package installs don't break as randomly as some pip packages, presumably because someone bothered to do more testing of commonly used packages included in the default package repository.
