Ninja Nodawa +2

NIN's best TP neck, it's not even close.
Sorry, but this is an incorrect take.
1) Obviously, if racc is capped Moonlight is better since Moonlight has more STP.
2) Even when racc is well under cap, Ninja Nodawa +2 can win but it's very close (like, single digit DPS difference in several spreadsheet scenarios I've tried). It does help Daken, which isn't to be ignored, but remember that Daken proc is only a 54% possibility (assuming max gifts) of one additional attack per attack round, and you're giving up STP+3 on every single melee hit AND Daken hit per round by dropping Moonlight. That's more significant than you're acknowledging, especially for the insane amount of multi-attack we're generally using these days.
As a sidegrade in the best of cases for Ninja Nodawa +2, and a clearly worse option when acc capped, I don't see a reason to replace Moonlight Nodowa (especially considering the likely seriously annoying acquisition/upgrade process).
The ninja HQ weapon was interesting, right up until the point where they tied yet another buff to remaining shadows. Historically, that's always been a bad idea with everything wiping shadows. It's like they didn't learn from mikage. You actually lose dps constantly reapplying utsu. So that 105~ attack bonus is useless basically.
It's a trash mainhand. Not close to Heishi or Kannagi, and only comes close to Kikoku (which gets Atk+60 base plus another 100+ Atk from easily maintained relic AM Atk+10%) when you assume you're always getting max shadow/attack buff. Even if acc was an issue, it's looking significantly better to use a better mainhand and a more accurate offhand (like Shigi)
HOWEVER... assuming all of the stats also work in offhand, Fudo Masamune may well be a very legit offhand option. I'm getting it as near BiS offhand to the RMEA mainhands in various spreadsheet scenarios even when attack capped (adding nothing from the shadow/attack gimmick), so if you're ever uncapped attack it's probably an easy win for best offhand.
You don't have to maintain max shadows 100% of the time to get a significant benefit - messing around on spreadsheet, I halved the max atk bonus just to simulate frequently losing shadows, and it came out well ahead as best offhand. Again though, all depends on whether that stat (and even the acc/racc+50) actually work on offhand.
Cue the people telling me that I shouldn't bother even attempting to do damage without BRD COR GEO max attack buffs and everyone is always attack capped on everything (which is insanely unrealistic, but I've heard it many many many times...)
