An advantage of the 13” is the lack of discrete GPU. If you don’t need one, you won’t have to care about tweaking for power consumption (like adding utilities to force disable it) and your laptop will be less likely to take off like a jet engine. I had to take the 15” to get the 32G RAM on the previous iteration, and it made me wish I could have had a 13” option at that time.
