I'm a big Apple stan, but I would rather get the Surface Pro 4. Apple is selling a $100 pencil, and couldn't even include an eraser?? (which Microsoft did)

Also, all the original reasons I thought I would want the iPad pro vanished when I used the pen (+ big screen) of the surface pro 4 and realized it was just alright. Not exactly going to start throwing away my notebooks and pen collection for a stylus and slightly bigger screen.

The Surface 3 is cheaper and will do much more than the iPad Pro.

Tablets are complimentary devices, not primary devices.
