Big fan of Welkin! Their IDE is great, and jam packed with features. I really love their debugger and their test suite manager. Makes it super easy to run tests and track code coverage. I also really love their editor tools like go to definition. They also have support for PMD which is great. They're always adding new tools and features and they are quick to answer any questions you post to their blog. Review collected by and hosted on G2.com.

Their tools are cutting edge, so sometimes right out of the gate things don't always work as expected, but they are quick to fix issues. Review collected by and hosted on G2.com.
