I chose WebStorm because its a mature and stable production that has every feature I could ask for in an IDE. It saves me time and catches mistakes. All my normal development tasks, including amazing VCS integration, can be done quickly from a single place. They continue to make updates and integrate popular tools and frameworks.

Some people might complain that WebStorm costs money, however it is a relatively cheap piece of software for the number of hours you use it. Definitely worth it!

All of JetBrains other products are equally as awesome and provide a common interface. I also use Goland, RubyMine, and CLion. I used PHPStorm for 7 years and loved it.
