I think display wise they are the same. The 1st one looks more elegant while the 2nd one have the swivel & tilt function. The 1st have 3 inputs (DVI,VGA & HDMI) vs the 2nd only having 2 ( DVI & VGA ). So it depends on which features you want more.
The 6950 have DVI + HDMI + VGA(via adaptor) so you are safe whichever monitor you use.
