I don't see Nurse as valuable or accomplished as Hamilton. He was this year, but you have to pay for the body of work and his late-bloomer status has to count for some sort of discount on Hamilton's contract. I see that as the high-bar limit rather than a true comparable. If I were Holland it might convince me to go from $7.75 to 8 or 8 to 8.5... but he's clearly not Hamilton in my eyes.
[PS... this will sound entirely contradictory... but I'm not sure I would trade Nurse for Hamilton either... I'm just saying its easier to justify getting paid for offense and Nurse's defensive play hasn't been consistent for long enough to to add big $$$ to his contract]
Nurse is younger so of course the body of work will be less accomplished but he was better than Hamilton this past year, played a much bigger role, and Hamilton was never more than a 21 minute Dman until these last two years playing alongside one of the elite defenders in the league so his contract is inflated as well.
Whether it's 8.5 or 9, Nurse is going to get paid big.
Personally, I think Nurse is worth 8x8 max because he just hasn't played at a top pairing level long enough and never in a "normal" season so these 8x9 numbers are a bit absurd but based on the market and the fact that he has all the leverage, he will likely get it if he wants to push for top dollar.
