The new model is not improving CPU performance (https://browser.primatelabs.com/mac-benchmarks). Also, losing the escape key is painful, and I still frequently use devices that don't have USB-C connectors.
I did an all-around comparison and chose to buy last year's model instead. I can't think of a previous occasion when a new Apple product was worse for me than the one that it replaces.
I own the 2015 basic 15" model and it is a great machine.
The 2016 model consumes much less energy for the same performance (see link in my post above) and the SSD speed (esp. in >= 512 GB models) is much faster. It also has built-in hardware X.265 decode (IIRC) so watching those movies will require less energy than the 2015 as well.
