Pick the Pixel 9 Pro Fold if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are ram, screen size, water resistance.
Pick the Pixel 9a if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are weight, front camera, pixel density, among others.
