Based on the screenshot in the article, the OLED model has longer playtime; Valve says that the LCD model has “2-8 hours of gameplay” and the OLED “3-13 hours of gameplay”.
Though they do also say that this is “context-dependent”, and I’m sure that you can come up with pathological cases for each. Like, a game that has a nearly all-white screen and runs at 90 Hz is probably relative worst-case for the OLED in terms of battery life, and a game that has a dark screen and runs at a locked framerate of 60 Hz is probably relative worst-case for the LCD.
