Aspire S7 vs Thinkpad x240 vs UH574

I have recently gotten access to the university laptop purchasing websites to replace my temporary Surface Pro and have come across what appears to be the three best choices:

The Lenovo Thinkpad x240 Touch, the Acer Aspire S7-392, and the Fujitsu UH574 SB.

Now, logically, the reasonable decision would be to get the S7. However, the Thinkpad and the Fujitsu are all avaliable for 220USD less and have similar specifications, so which one should I get? Spend more for the S7's better overall design or opt for the others?
