I got to use MagSafe for a couple weeks when I was testing between the 2015 and the 2017 MBP and I think the MagSafe was a brilliant idea and liked the light to let you know charging was complete. I settled on the 2017 thought because the display and sound speakers were just so much better. I almost want to buy the 2015 just because it’s a classic laptop with great useable features like MagSafe and extra ports USB too.
