Dell xps 13/ lenovo t450s- Which one?

Which one would be a better buy for me? For work outside of office, connecting to external monitors. Using matlab, c++, some basic 3D graphics.

dell xps 13
13 inch
i7 (5500U)
256 ssd
8 out max 8 gb ram
3200x1800 touchscreen
Intel HD Graphics 5500

OR

Lenovo T450s
14 inch

500 gb HD
8 out max 12 gb ram

If you have money then Dell Xps because it is a good looking laptop and it does matter but T450 is an ugly looking great work horse which is known for their reliability.
