I have had the opposite experience personally. Any non-trivial application I've deployed has been a lot more complicated with PHP than anything I ever experienced with Python.
Asyncio really makes a difference here. I also hate that PHP has to spin up with every single request. This is something I have never gotten used to (From my understanding, most Python web frameworks just give you a clear/fresh Request Object, which is so much better even with WSGI (unless you're using WSGI scripts) Much easier to maintain application state this way in my experience. PHP-FPM doesn't exactly solve this problem, I don't think).
