This is purely based on my experience!
I use PHP way more often for just plain CRUD applications, which are redundant, or like CMS for small-medium enterprises. Not only it speeds up my development time, it has hell a lot of support too.
I use Nodejs, simply to see Websockets. I don't see any other way to use Nodejs, as pretty my PHP/Java does the job for me. Maybe I'm a noob, that's why?!
