I would recommend the monitors if you're only buying 1 or don't mind them being slightly different.
I got 2 monitors and they are both crisp and clean looking; awesome looking
When I put them next to each other on my (level) desk, for some odd reason the one on the left is a little bit taller than the one on the right; I got 2 of the same monitor so that everything would look neat and clean.; this kind of ruined that.
