Now, if we dual wield Skeggiold, we have DEX+4 STR+4 ACC+8 ATT+12
If we Man/Skegg the ACC one we have DEX+4 ACC+13 ATT+18.
If we Man/Skegg the ATT one we have STR+4 ACC+5 ATT+30.
"sh*t is situational" comment here.
Round about comparison: (leaving out crit since its quite variable)
From base of just D49(real rough)
Dual Skeggiold: 1 fSTR = 1.7%, 10 acc = 5.5%, 12 att = 3%
Man/Skeg(acc): 15 acc = 8.25%, 18 att = 4.5%
Man/Skeg(att): 1fSTR = 1.7%, 5 acc = 2.75%, 30att = 7.5%
Just from this I'd say you'd get more milage out of Man/Skeg(acc), esp. if A+ and A- weapons continue to get futher apart on acc as you go up in level. But if acc is capped from sushi, the att one could be pretty nice too. Unless they change something, the difference will be huge at 99 and no one will be thinking about anything but A+ weapons anyway. It's nice that SE is trying to bring axe/axe(sexy) back. Perhaps we may even see a wardrobe malfunction.
