As far as i see, Rine sausage is just usefull to counter Kakuzu Online with his Chaos proc. As Kakuzu deals only nin dmg. In any other fight, rine sausage seems like *. Would not invest in him at all. Just wait Madara. 6p Naruto is just upgraded version of Kurama link, so if you have that or closing in on SR from GNW then no point of getting him. But i would say sausage, unless you like him that much no point of getting him. Only sausage thats playable is skill experiment Susano. As he has better dmg, more immunity and scaling.
