Visual Studio is out of scope, but what about Visual Studio Code? It's very different from Visual Studio. With the right extensions, it makes PHP programming fairly delightful.
My problem with PhpStorm is the price tag associated with it. I am not paying over $100 per year for an IDE. (I'd be Organization Use, not Individual Use)
I personally use Aptana Studio 3, but it hasn't gotten too much love in the last few years, so it only works well through PHP 5.6. 7.0+ isn't supported, yet. It's still my favorite out of all of the IDEs I've tried.
