Samsung 940N or BenQ FP91G+

I just bought a new setup and was supposed to get the benq fp91g+ 19" LCD monitor

I got a call saying everything was ready but the monitor wouldnt be available for another few days and would I like the samsung 940n 19" LCD monitor instead, that way I could get it today. me being the patient guy I am of course I took the samsung that day, but shortly after realised that it doesnt have DVI input.

the benq has:
250cd/m2 brightness
550:1 contrast ratio
8ms response time
D-Sub and DVI-D inputs

the samsung has:
300 cd/m2 brightness
700:1 Contrast Ratio
8ms response time
15pin D-sub

so to my question,

is it worth my taking the samsung back so i can get the benq monitor with DVI input?

or should i keep the samsung with the analog input and the better brightness and contrast ratio?

Well, I've run DVI and VGA side-by-side on my 4-monitor rig. Both monitors were the same model and both had the same model video card (Quadro NVS 280)... I checked the screen with a magnifying glass and could see zero difference. Therefore, I think DVI is overrated... but then again, I'm not a gamer.
