I have a 2013 15" MBP. It's holding up really good till now, only the performance and the battery are affected negatively, but still not enough to warrant an upgrade. It's the first laptop I didn't need to replace after two years. The biggest upside is the trackpad, which I use extensively. The display is very good if you can deal with glaring. It's more durable than most plastic junk that I used before. I can't recommend the new Macbooks, since there are in total too many downsides: Keyboard, lack of Escape key, no magsafe, price policy, T2 and dongle lifestyle.
