I am mac user for a log time now, but on december I bought the i7 Surface Pro 3 and I can tell you that I absolutely love it, the only think i don't really like is Windows 8, but I've gotten used to it and I really think Windows 10 will solve most of my issues with Windows. For me as a student it has been a great device, really portable, office programs are much better than on mac, the ability to take notes is amazing for me at least as I use it a lot to mark up PDFs. The keyboard even though many people don't like it, once I got used to it I can write really fast and have no issues at all, the trackpad I find it really responsive but it's too small so I usually carry a mouse or use the touch screen.
Also I have ordered the new 1.3 Macbook, and I really love it, and my only concern is that I hope the computer runs smooth but with no lag. I do think the Keyboard and Trackpad here are vastly superior.
So for me if you think you can value the tablet mode, and the inking give the Surface Pro a try, if not I would go for the Macbook
