Using TDS is like going from the Flintstones to the Jetsons overnight
With TDS
Local databases prevent collisions, while continuous integration and automated deployments have been made easy. Developers can employ a full audit trace on Sitecore items, reverting changes is simple and quick, and Sitecore items and source code move together. Leveraging Source Control means that the constant changes made during the course of a project merge seamlessly, and that new additions to your team are quickly brought up to speed.
