In my experience, conda breaks quite often. Most recently, conda has changed the location where it stores DLLs (e.g. for PyQt), which broke pyinstaller-based workflows.

In principle, it's a good idea; in practice, I'm not satisfied. On Windows, it's an easy solution, especially for packages that depend on non-python dependencies (e.g. hdf5).

My main problem with conda is that it's super slow.
