I can't help you with comparisons because I just put a pair of ND's on mine from the old stock tires. My first set of tires.

How many miles did you get out of your ND's? I don't have 1000 miles on mine yet but man I love the way they stick.

To the posters asking about getting tires mounted I pulled mine and took them to the local Harley shop. You should get new rim rubber and tubes if you have spokes so add a bit to your budget. I got quotes of 30 to 60 bucks without tubes. A couple of places would mount em for 20 bucks if I bought the tires there. Everyone was so far away that it was going to be a two day affair but my local Harley shop is 3 miles from my house so convenience won out and I got em both mounted on a Saturday. Getting the rear aligned and the belt tension right was an interesting lesson. Not hard just different.
