Favorite among whom? This is a very broad statement that isn't broadly
true. There are many Yaws users out there, many Mochiweb users, and I
bet there are more than a few who still use Misultin.

IMO Cowboy is popular among folks who need a library-like HTTP server
and who also like to be leading edge, but not everyone falls into that
category, not even close. Also, there seems to be some ongoing rumor
that Yaws can't handle library-like HTTP apps, but that is entirely
untrue.

This statement is slightly confusing. The phrase "Cowboy provides
this" could be taken to mean "Cowboy provides Webmachine", which isn't
true. So just to be clear, what you really meant was that Cowboy
provides assistance for writing RESTful web services.

This is another unfair generalization. I've never been an Apache user,
yet I've used Yaws for everything from regular websites to embedded
systems and it's always given me just what I needed.

At about 11 years old and still going strong, Yaws is popular among
users who need a system they can count on to provide years of
production stability, backwards compatibility, and consistent support,
all while keeping up with the latest Web developments such as
streaming, long polling, WebSocket, and Server-Sent Events.
