Unlike 2017's Galaxy S8 and S8+, there's a bit more differentiation between the Galaxy S9 and S9+. You'll see a secondary camera on the back, plus more RAM, and of course that larger screen and battery. That gives the Galaxy S9+ a bit better value proposition at its higher price, but may leave some who want the more compact Galaxy S9 feeling hard done.
Here are the complete spec sheets for the two phones.
