Not the OP, but I have a 2015 Macbook Pro and a desktop PC both running Linux. I love Fedora, so that's on the desktop, but I followed online recommendations to put Mint on the Macbook and it seems to run very well. However, I did need to install mbpfan (https://github.com/linux-on-mac/mbpfan) to get more sane power options and this package (https://github.com/patjak/facetimehd) to get the camera working. It runs better than Mac OS, but you'll need to really tweak some power settings to get it to the efficiency of the older Mac versions.
