Gamma Burst Flash vs. Final Shine

Which modification of Final Flash did you prefer?

I just noticed these two are kinda similar. Is Gamma Burst green too? The name makes me think it is.

GBF has a weird hand stance that tries too hard to be different, while Final Shine looks like a generic 1 hand ki blast. Probably FS even if I have no idea when it was ever used or why it exists.

Gamma Burst is yellow in the full color manga and in Heroes where it has been employed as SSJBE Vegeta's Ultimate or Super blast.

I Really like final shine, it just looks so beautiful, plus we don't get a lot of green ki blasts in db besides broly.
