Compare image recognition frameworks using deep learning on iOS

Hi I'm very curious about how well deep learning framework for image recognition work on iOS device. I see many options out there now, so it would be great if we can get a comparison of the accuracy and performance of them. The options i found are:

1) Tensorflow (https://github.com/tensorflow/tensorflow)

2) DeepBeliefSDK (https://github.com/jetpacapp/DeepBeliefSDK)

3) BrainCore (https://github.com/aleph7/BrainCore) - though it seems that it doesn't provide pretrained model, or it's just that I didn't see it.

4) Torch (https://github.com/clementfarabet/torch-ios)

5) DeepLearningKit (https://github.com/deeplearningkit/deeplearningkit/)

You are very much appreciated to answer even if you have worked on only one of them (then together we can amalgamate a complete comparison). Or if you know another framework that you would like to share that would be great too!
