Is the final kamehameha stronger than the big bang kamehameha

Well Vegito used the Final Kamehameha as a Super Saiyan and Gogeta used the Big Bang Kamehameha as a Super Saiyan 4. So judging by the characters that they are used by then the Big Bang Kamehameha wins hands down.
Then of course, the Final Kamehameha failed to destroy a weakened Buu but the Big Bang Kamehameha almost destroyed a fully powered Sin Shenron and if the fusion hadn't run out just as the second was about to be fired it would have finished Sin permanantly, something that only the Spirit Bomb with energy from the entire universe managed.
Therefore the Big Bang Kamehameha was far more powerful.


Actually SSJ4 was used in this therefore powering up the Big Bang Kamehameha SSJ gogeta is known to do it but cannot for some reason the creators didnt add it in Final Kamehameha failed to destroy buu yes and sin shenron is indeed stronger but Gt isn't official so SSJ4 couldn't hardly exist But if they fused against Buu by fusion dance And did the big bang kamehameha It wouldn't destroy buu either but if GT were offical And Vegito was in it and could go ssj4 than there would be a difference Big bang attack is weaker than final flash Kamehameha is powerfull and I belive it was said that The potara fusion was 10x stronger than the fusion dance (I belive so if im wrong correct me) Thus resulting in Final kamehameha With ssj4 Vs Big Bang Kamehameha in ssj4 There wouldn't be much of a power difference but Final Kamehameha has slight more power than big bang kamehameha
