What does conda give you that is so much better than venvs?
On the distribution side, we are a small academic group that provides a niche, binary, scientific package that has quite a few binary dependencies (things like hdf, netcdf, etc.). We do not have the human effort to provide support for different distributions of Python, but it is very easy for us to say it will work if you use Anaconda with this environment on multiple OS's.
Poetry feels better, if only because it separates out explicit vs transitive dependencies.
So use https://github.com/mamba-org/mamba , which is an alternative client to conda and a million times faster. (If you are creating environments more than once per month or so).
