If you are writing 'standard' blocking, synchronous code, I am not sure
why you would use any of the above.

I know nothing of tornado. I personally would use asyncio over twisted
if I could because it is simpler, in the stdlib, has the option to write
'untwisted' non-blocking code similar to blocking code, and the docs
easier for me to read.
