Preta Path would get destroyed in a physical battle. That is the hard counter to the Preta paths ability, it was stated in the war.
Also no, Deva Path is not strong enough or restrain him, he needed CT to trap the 8 tails after getting overwhelmed by the 6 tails(which is weaker than the 8 trails btw). My argument rest on the 3rd Raikage beating the Paths before pain goes for the nuclear option
