"productivity is equally as important"

Node has a lot of good features, but programmer productivity isn't one of them currently. There are close to zero full-featured frameworks with "the works" (Geddy comes close, but is no longer maintained, and Express is essentially no more than a mini-framework). You simply have to write a lot of code yourself to do stuff that in other frameworks such as Django is included by default. Add to that the fact that deploying a Node site isn't nearly as easy and fast as deploying a PHP site, and you've got a setup that isn't ideal in terms of productivity.
