Sersi vs Quasar

I don't believe this has been done, so discuss.

Quasar. Way more verstile and has a supposedly unlimited supply of energy at his disposal. Q takes this one

So does Sersi, hello eternals are consider comsic beings. Sersi is probably the second most powerful avenger behind Thor. Sersi powers are sick, matter transmutation, metabolism increase, strength increase, indestructible, teleportation, teleakeniese, telepathy, pisonic force shield, control all form of energy. Sersi beat the shit out of the avengers and knock out immortal hercules with one punch, and took out a sentry robot with one blow. Sersi all out will kick the shit out Quasar.

Sersi by a tiny margin. Maybe 5.5-6/10.

Quasar. His bands also are a source of knowledge which is a weapon against a telepath.
