Note 3's camera is a hit-and-miss. Mine takes fantastic pictures, but another guy's Note 3 took pictures that came out worse than my old Desire S. He ended up going for a 1-to-1 exchange and the new set at least came with a camera that worked properly. Wait a while for the Note 3 teething stage to settle before making a judgement on whether it's worth it to consider this device. Its camera will definitely not match the 1020's if that's your main consideration. I don't think it even matches the 925's.
N3 camera options are nice, but overall quality the N2 was better IMO.
Higher megapixels does not = better. Sure N3 has higher MP, but the processing time and focus takes longer and the N2 just snap and the results are outstanding pictures nearly 100% of the time. The N3 on the other hand, the yield of great pictures is much lower, more like 60-70%.
Therefore, N2's camera was better. But hopefully with some updates the N3 camera will get better? (hopeful speculation....)
