An obvious choice, in my opinion.
It's honestly puzzling why some of the earlier handhelds came out with 144Hz/1440p/OLED displays which weren't capable of VRR, given the low wattage APUs used in most of these systems. VRR was practically developed for this exact scenario, where you're limited to 30-45 FPS and need the display to dynamically change its refresh rate, to prevent ugly screen tearing.
LCDs tend to hold up much better in bright ambient conditions than OLED displays, which is obviously useful for a portable device.
Wasn't Asus who solved this VRR+OLED problem with their ROG G14 laptop?
