aiohttp is an excellent library. very stable. I concurs, but! it's too heavily tied to HTTP/1, and well, I am not a fan of opening thousands of TCP conn just to keep up with HTTP/2 onward. niquests easily beat aiohttp just using 10 conn and crush httpx see https://gist.github.com/Ousret/9e99b07e66eec48ccea5811775ec1...

fwiw, HTTP/2 is twelve years old, just saying.
