Question: This, and many other posts, suggest that PyPy is the way to go (as a user). Faster and compatible - what's not to like? But elsewhere I read, 'hold on'. It actually isn't faster with things that use a lot of C optimizations (like numpy and pandas, which I use extensively). I don't mind small startup JIT penalties, but I don't want to have my core code run more slowly, or fail. Is there a simple direction? (ie: Use standard cPython or use PyPy) Or is it, as always, 'it depends'?
