This link should be useful for your case: https://www.eventbrite.com/engineering/what-version-of-cassandra -should-i-run/ 3.0.4 comes with a ton of features from 2.1.x which is considered to be most stable. Datastax Enterprise is using 2.1.13. Version 2.1.x and 2.2.x will be only supported till Nov 2016. In my opinion you would be better off opting for 3.0.4 version.
