Unity3d is not good for product based app like snapchat?

Last few year i am working on augmented reality based product apps. But i found that unity3d is not good platform for product such as snapchat. Native app development is much better for hybrid app in terms of performance and quality.

@sumit9236 I am not sure what you are after here. If it is for an answer, I would say no, I personally never had issues making hybrid AR apps with Unity.
You can use OpenCV, Vuforia, ARToolKit directly from unity platform, it is quite practical.
