I said their precision not attack power of their attacks. Here so you understand what i said:
Darkseids omega beams can erase targets from existance.
Gokus kamehameha can either destroy a target but will still exist but will obviously be dead.
As for MUI darkseid can match it so no use in the automatic dodging even if stats werent equalized he wouldnt have a problem dealing with MUI afterall hes stronger.
