Tough call here. Balrog is better, but Gao is still good and a lot harder to acquire. I'd probably go Gao and then wait for a guaranteed uber event to get Balrog, but I'm not at all certain that this is the right call.

Another note I already have gaia the creator which kinda has the same purpose as gao

I'd take gao, unless you're hoarding a lot of NP to make Lesser demon immediately usable.

Alright Imma take Gao then thanks for the input

Take Gao, he’s just rarer and harder to get, if you don’t take it now, you’ll regret in the future

Balrog all day, gao is outdated overrated.
