I think you mean the J15 sir.Rafale is at least somewhat stealthy From the front quarter, almost certainly substantially more so than F-18, J-16/Su-33 and MiG-29.
The biggest Operational advantage the Chinese could have gained using primarily J-16/Su-33 is a potentially massive Unrefuelled range that practical truly stealthy carrier aircraft, or any Other existing carrier aircraft, will likely be unable to match. So I think strategically it is more important for the Chinese navy to deploy catobar carriers, AEW aircraft, integration with satellite and other reconnaissance platforms, with J-16 then it might first appear.
Also, if a navy deploys a mix of truly stealthy and unstealthy aircraft from carrier decks, then j-16/Su-33 would have another advantage which would only have been shared by the now defunct F-14. That is it is a very large aircraft able to accommodate a very large and powerful radar, far larger than f-18. Rafale and MiG-29 can handle. Collaboration between non-stealthy tactical aircraft with very powerful radar and all-aspect stealthy Aircraft is probably the way to go in the next 10-20 years.
