The only advantage I see the Pavillion having is a normal USB port, while if you're willing to use the type-C and included dongle with the Spectre is no issue but you get Wacom compatibility...which I think is a pretty huge deal.
Definitely leaning towards the Spectre now, doing some research on it and various Wacom pens.
