Which should you buy?
The MPG 321URX is the clear pick on raw spec strength, leading by 14.2 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
The PD2730S doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
Pick the MPG 321URX if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are refresh rate, peak brightness, response time (gtg), among others.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: the MPG 321URX is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
