So Gogeta scales at least 20x above baseline because Syn was baseline, Omega was ten or so times as strong and Gogeta made him look like a joke. To bully someone in Dragon Ball and tank their blasts, your ki is said to need to be twice as powerful as theirs at least.
Moro scales to a Omen Goku stated much stronger (in blue) by Moro himself, possibly stronger than ever as hinted by 18 and Piccolo which would put Goku at least twice as high as before. Since each GoD is casually baseline, Jiren is notably stronger, MUI beat the crap out of him and this Omen Goku might be above that that should make Goku no lower than 3x 3-A. Any lower would be really dumb.
However, Moro fights with techniques and skills Gogeta's never dealt with. Paralysis magic, energy absorption, illusions and fear manipulation among his other magical abilities like his lava blasts from Naemk, the full body lasers he showed last chapter, the telekinesis he used on Vegeta, mouth beams that took off Grand-Kai Buu's head and scratched Merus and his gear and more.
In terms of intelligence and skill, Gogeta should be a decent bit ahead of Moro in physical combat especially since he's probably stronger but Moro would outsmart him and has a plethora of abilties that could help him win the fight.
