They're so close I think it comes down to either personal taste, or the graphics you're used to...
A music Professor used to always play his first year students different music recordings. When he first tried this experiment, his students generally preferred music on records over cd recordings. With time he noticed that students preference changed to the mp3s bitrate. It also turned out that students preferred the sound from compressed mp3s over uncompressed music files.
This lead to the idea that people generally prefer what they're familiar with.
Preference for graphics may come down to familiarity when the difference is small enough.
