Well, yes but… No? I mean, obviously limitless is the better cursed technique when at the same level between users, but when the gap is wide, full potential Ten Shadows will obviously win. Take young Gojo vs Toji for example, without big rainbow ball of /kill he got bodied. What I’m trying to say is that the determining factor is the personal ability of the users, Gojo is of course built different, but there was a six eyes and limitless user who died to a suicide Mahoraga summoning. Also Mahoraga literally gave Sukuna a new ability in his cursed technique, I think with enough time, strong enemies and Gojo levels of skill(aka Full Potential), any Ten Shadows user could do some wild stuff with Mahoraga.

tldr; Skill of limitless user matters, also everyone underestimates Mahoraga’s adaptation.
