Who should buy which

Pick the AW3426DW if you play fast games, have a standard desk, or want a screen one strong graphics card can feed at high frame rates: 3440 x 1440 is far lighter to run than 5120 x 1440, both HDMI 2.1 ports reach the full refresh rate for a console, and the stand adjusts in height, tilt, swivel and slant. Pick the Odyssey OLED G9 if you play racing or flight sims, or want two full 1440p workspaces side by side with picture-by-picture for two computers. Measure first: the G9 is about 1.2 m wide, and its stand only adjusts in height and tilt.

Yes, per frame. 5120 x 1440 is about 1.5 times the pixels of 3440 x 1440. The G9 caps at 144 Hz, which keeps it reachable, while the AW3426DW can go to 280 Hz if your graphics card keeps up.
