Are you going to make use of your return window? While waiting for the release of the new MBPs, for the past 6 months I have relied on a Surface Book machine. Now that my TB MBP arrived I thought I was going to happily switch back to the cosy and familiar macOS environment. And you know what? After a few days with the MBP / macOS, I do not feel anymore that it offers a superior experience compared to W10 on a full touch device. Both operating systems offer a similar level of comfort at the moment. But when you add to the equation the Surface Book with magnetic charging, usual ports, SD card reader, comfy keyboard on one side, and the compromised MBP design / connectivity on the other the outcome for me is clear - the MBP is going back to Apple next week... I never thought I was going to feel this way.
