Nihilus can not lose from somebody powerful in the force, because he eats that power and stnengtens himself while making the other weak.
What proof is there of that? If he could do that then why didn't he do it to Darth Traya? Instead, Sion just beat her up. Heck, why wouldn't he just do that to Sion too?
Nihilus needed Sion's help to cast down Traya. Both wanted to humiliate her, no kill her. They thought death too good for her. Note that Sion lets her live twice.
And Visas and many others tell you that Nihilus drains the hell out of Force sensitives. He feasts off of them. It's why he destroyed Katarr and why he came to Telos, though Kreia lied to him about that.
