I upgraded 13 Pro Max to 15 Pro Max. There was absolutely nothing wrong with my 13 PM, though I went ahead to see how I liked the 15 PM. The battery (which was amazing on my 13PM) is about the same, though the 15 PM is noticeably lighter and a hair smaller in size - yet has a larger display by reducing the bezel size. The display is slightly better and overall it is slightly faster as well. After having the 15PM for a couple days, going back to hold my 13PM felt like a brick (& a bit outdated) in comparison. The 13PM is solid for sure, though I’m definitely enjoying my 15PM! Answer from Jes_32 on reddit.com

“True” that could be subjective , is there spec and slight design changes? No doubt. At minimum you’ll get a fresh battery. It will be a little upgrade. I do like the titanium better over the steel.
