What are you recording from (video camera, DSLR, digital camera, TV, etc.)? Is this for game capture from the PC or are you recording something else? For portability the Atomos Ninja 2 would be better if you are using a video camera, DSLR or digital camera. File transfer from the Ninja 2 should be an easy process since all you have to do is copy the files from the device to your PC. Really it depends on how and what you are recording.
