Like others have said the Nula is on a different level in terms of balance, and finish but that comes with a cost. As far as accuracy goes I have no doubts that the Nula's are great. I happen to get one that is pretty finicky eater. Very few loads produced MOA in my Nula I did find one that would group right at .7-.8" consistently for 5 shots but overall I was disappointing with the accuracy of the Nula and I am considering sending it back for a rebarrel. With all the praise that they get I was surprised that the accuracy was not better.
On the flip side the 3 kimbers that I own, with all the problems you here about them, have been great in the accuracy department and flawless everywhere else as well.
This is how I see the two in a head to head comparison
Fit/finish NULA
Balance NULA
Accuracy NULA (overall not just my sample of one)
Value Kimber
