Out of scope: Azure Database Development.

I am trying to decide between Visual Studio 2015 Database projects and SSDT. 

I am using Visual Studio 2015 Database projects to develop and source control my SQL 2014 database application.

I understand that SSDT also provides a comprehensive and rich set of SQL database development features.

Which one of the VS15 DB Projects or SSDT are more powerful to developer SQL 2014 application.

I wish there was a comparison table that compares the two tools.

**Conclusion**

Based on the answers I understand that the two are very similar. Before this post, I was confused and I though they have a different set of capabilities, which is not correct.
