Is gohan stronger then Goku

Depends, since Gohan always released his "inner power" and Goku is always training. Gohan Surpassed Goku's strength during the fight with raditz, when he turned Super saiyan 2, and when he got his power fully released by the elder kai. But after the fight with buu, Goku should be stronger since Gohan barely trains and studys to become a scholar
