Yeah I think Trunks would win this. Gohan in Base form could handle him as a SSJ, so Trunks might not have been all that tough. Gohan with one arm should be on the same level as Trunks when he fought Frieza and I have Trunks at his debut at 4 million so I put Gohan around that marker. Put Trunks a little bit lower and divide that by 50 at least I've have him around 60K which in Ginyu's words would be enough to thrash the Ginyu's the way Goku did.
