I was in the same dilemma (although switching from a 2011 MBP) and decided to go with the older 15" Macbook Retina. I would never go for a touchbar over physical keys, and definitely don't see any reason to pay a hefty 400-500$ extra for the base model just because Apple decided to increase prices. I'm extremely satisfied with this decision, would suggest the same. The 15" MBPr is a beast.
