Macbook pro 13 or Surface Pro 4?

I love the Surface pro 4 but I am afraid it wont last me my 4 hour class let alone the day. I am still within the return period and wondering should I try out a MacBook pro? For $47 more I can get the base model of the MacBook pro 13 with retina display. I just took off my surface pro 4 the charger and it is at 93% after only 30- 40 minutes? The notification says I will have 6 hours left but I am wondering am I better off with a MacBook pro? As far as my major goes it is culinary so this won’t factor in my decision but I’m not sure if I want a MacBook or the Surface pro 4.
