I'd say overall, I like Face Down single better. I really love the track ひとりじゃないさ (Limited Ed.) and also 目指した未来へ (Regular Ed.). The whole tracks in Face Down single satisfy me! I'll give it 10/10!
On the other hand, in the Your Eyes single, I only like 'Your Eyes' track only. The others songs are not really my cup of tea. But I think 'Voice' from the limited ed. isn't really bad either. I might start liking it from now on, maybe... For now I'll only give it 7/10.
