Express, Koa or Hapi for today’s node newbies?

Today, to somebody new to Node and programming in general, which framework would you recommend learning, Express, Koa or Hapi? Express seemed to be the go to Node’s web framework a while back. Is it still the case these days?

Although I read several discussions supporting all of them I found opposing arguments some of which are:

- In spite of being extremely popular Express slowly getting obsolete, not being as much actively maintained as in the past and that implementing ES6 changes would be better done in a new framework. (As per Express site, version 4.14.0 supporting Node.js 6.x. was released on June 16, 2016)

- Not fond of Koa generators

- Hapi being too complex and requiring too much code for small projects
