So if money wasn't an issue, would you have gone for the Dell? What makes the Dell better than the Samsung, or is it negligable?
Depends on what you need from it.
The Dell has more "features" and superior viewing angles.
If you want it for DVD viewing then the Dells' viewing angles would suit you.
If you just want it as a gaming monitor ( and save ~£100 ) then get the Sammy.
There are more indepth threads here about both monitors.

Edit - Answer to your question = Unlimited budget then the Dell , but more than happy with the Sammy
