I had a 2014. It is a great laptop, no doubt but I recall before several patches I had issues w/ USB 2.0 port connectivity. I had the screen replaced once. So it wasn't without its own set of bugs. Working beautifully now.
My only beef is no NVME and it stutters a tad. If I could find a 2015 w/ 16gb/1 tb spec w/ NVME...
I'm hoping the glitches in the 16" can be worked out, eager to see how the 14.1 will look...
and I know Apple kremlinology is never the most accurate way to look at things, but boy were the Mansfield/Forstall years great...
