title: What is the difference between Eclipse with Spring IDE plugin and Spring Tool Suite alone?
body: <p>What's the difference between these</p>
  
  <ul>
  <li><a href="https://eclipse.org/downloads/">Eclipse</a> with the <a href="http://marketplace.eclipse.org/content/spring-ide">Spring IDE</a> plugin</li>
  <li><a href="https://spring.io/tools/sts/all">Spring Tool Suite</a> (STS) alone</li>
  </ul>
  
  <p>I ask because STS says it's built on top of Eclipse, and I wonder what differences it has over simply using a plugin that adds similar functionality to "vanilla" Eclipse.</p>
