I'll disagree here a little
They're all good boards and despite the extra you pay for the higher end boards you listed they do perform well under OC conditions. However the extra chipset cooling hardware on the UD7 isn't that efficient.
And the UD3R is a popular board simply because of it's price/performance ratio and it's just as stable.
The main difference between the boards is basically the chipset cooling hardware and features with the higher end board offering a little more for the OC enthusiast.
