Looking at the negs, both seem fine for printing.
In fact, just to show you I have attached a very basic inversion of the neg to positive in my PShop LE version.
As said, scanning can add various things and can quite often leave you with a positive you are not happy with, and then immediately you think that it's a problem with the negs, when it's NOT!
Oh, and turning off the RGB colour mode for b/w pics helps. Change it to greyscale and it looks (slightly) better straight away.
