Comparing image synthesis methods

In this study, we are evaluating the fidelity of different images synthesis methods.
You are presented pairs of images, one of which is real image randomly selected from the dataset while the other one is a fake (generated) image created by our models.
Please click on the one that you find the most likely to be the real image, i.e. the most realistic, with the least visual defects, or the most pleasing and natural to your eyes. If you cannot make up your mind, pick the last answer.
A new pair is shown after each click, as an endless stream. You can stop at any time.
Thanks a lot for your help!

I cannot decide: no obvious winner.
