It was implied Gohan could get most of his powers back if he turned into SSJ, and 1st form Freeza still stomped him, so Freeza 1st form would already be enough to win round 1 and 2.
Kid Boo wins in the second round, since base Goku (vs Rild) was already stronger than Boohan and Omega Shenron is on a whole different level compared to this Goku. Unless Freeza can access his final form.
