personally I have JS experience (browser/node.js), as well as asio in C++/Boost, EventMachine in ruby and Twisted/Tornado in python. I strongly disagree that people who dislike asyncio only do so because they don't like the event loop. That just sounds like a typical quick dismissal of criticism. No, its a objectively awful convoluted API.

But if you think you can write correct asyncio applications of any significant complexity, that's great. Doesn't change the fact that a lot of highly experienced developers struggle to do so.
