IMO the most important part to look for when buying a TFT monitor is the panel that it uses.
The most commonly used ones are the TN, MVA/PVA and IPS panels. Try searching for the pros and cons of each one. A good site to start with is
http://www.prad.de/en/monitore/index2.html with lots of reviews, a FAQ and a buyer's guide among others.
As I see from
here both the panels you are referring to, have a TN panel, a thing that, in my opinion, is not so good when you are interested, as you say, in an above average image - colour quality.
A good guide can be found
here too.
If you have the chance to go and see the monitors that you are considering buying, go for it without a second thought. As much as you read, your eyes are the final judge.
