I had two P95f+'s both were sent back due to distortion on the very bottom 1" of the screen. Aside from that problem the + was a decent display but I have seen better. I would take the Sony G410 and Samsung 900NF both over the P95f+.
Judging by the information i would say the + series would be better simply since it has a higher maximum resolution. It's pretty easy to judge a monitor by it's specs.
Not true, Spces tell you nothing about the monitors geometry performance, color viberance , brightness/contrast, sharpness, convergence, ect.
