#1 Independent circuit

A move to independent circuit tops the list because of the kind of impact Dean Ambrose can make if he decides to work as an indie wrestler. Dean Ambrose will have the flexibility to use his star power and make a good name for himself.
The independent circuit provides him with a lot of creative freedom to his character, something which Chris Jericho has used to the maximum effect in the recent past.
Dean Ambrose is a big name and he could capitalise on this opportunity to have high profile matches against already established superstars in the indie circuit. There are reports that ALL IN 2 is scheduled to take place on August 31 and Dean Ambrose on the match card will certainly help the event.
Dean Ambrose vs Christ Jericho could possibly be an interesting match between two former WWE superstars on a platform that challenges WWE for its hold on professional wrestling.
