For my game's better performance, should i use Starling?

I heard that using Starling gives better performance than just using Flash pro Native (GPU mode??) when playing flash games on smartphones.

However, according to this article, there is not much difference between GPU mode and Starling although its recorded in late 2012.

My game is tile matching game that uses vectors and many different tile pictures. also upto 64 tiles can be present at the same time.

I don't know how much more performance Starling would provide, but if starling would give more performance, i don't know if its worth the time and effort to learn how to use Starling and change my current codes to use Starling?
