I own the basic 2015 15" model and it works really well. The discounted price difference between the two models is $400. The 512 GB 2016 model (as opposed to the 256 GB model) has SSD read benchmarks that are considerably faster than the 2015 model if that is important. The 2016 model is somewhat smaller and lighter and the battery life is about 2 hours longer. I like the keyboard on the 2016 model and many seem to like it after they get used to it. For me the MagSafe adapter is annoying because after a short time it start to fall off if it is hanging over a table edge. The power adapters on the 2015 and earlier models have problems with the insulating material coming off. The 2016 model has a replaceable cord that detaches from the power brick. The 2016 models can drive 5K displays.
