Very good question...now by aesthetically pleasing do you mean, the coaster layout itself, its theming, its location, or all of the above?
Nemesis Inferno made my eyes water when I first say it, I also really like Sheikra's interaction with the theming. The Hulk looks beautiful with its cobra roll over the lake...the list could go on. I think we'd be better of discussing which coasters look the least aesthetically pleasing :lol:
