I always opt for open-source when available, but after having used JetBrains&#x27; PHPStorm for PHP&#x2F;CSS&#x2F;JS&#x2F;etc, I can&#x27;t even pretend Eclipse is still a viable solution.<p>Although the community version of IntelliJ at PHPStorm&#x27;s core is open-sourced, PHPStorm itself is not. Regardless, the productivity gain it provides is WELL worth the cost and inconvenience.
