[Traison]

Claws offer 7 less acc, 23 less skill speed, for a +26 determination. You can easily make up for the lost acc elsewhere, so you're left with -23 skill speed, +26 determination. There is a very clear winner here, and skill speed is not it.

First I gotta say, assuming from your use of "7 less Acc," might you be talking about regular Sphairai and not the Zenith? Cause if so then yes the Hellish Claws beat them every single time no contest, even under Acc cap. If not, it is a 11 Acc difference.
I'm using these stat weights. I don't have a number for accuracy so I am going to plug a random number in at 0.8 since it sounds like a reasonable weight before cap (Even though it is probably much higher.)

WD 7.841
STR 1
ACC 0.8
DTR 0.224
CRT 0.172
SS 0.154

Sphairai Zenith:
WD = 46*7.841 = 360.686
STR = 31*1 = 31
ACC = 37*0.8 = 29.6
SS = 26*0.154 = 4.004
Total: 424.982

Hellish Claws:
WD = 46*7.841 = 360.686
STR = 31*1 = 31
ACC = 26*.8 = 20.8
DTR = 26*0.224 = 5.824
Total: 418.31

So under Acc cap, point per point, Sphairai is better weighted. When you start considering other factors such as gear and food, then it might not be better, however compared to the Claws, it is better.
