my question went unanswered so i would like re-ask again since i'm totally new at this point when it comes to the phone. I did some research but still unclear on the matter for the moment. So i was hoping you guys could shed some light before i make the final jump for getting the phone

ok since i'm free come i help you,
G version
benchmark 10% less
but currently more games are compatible with it
because the graphics chip used is older version and not the samsung version.
Even so the performance shouldnt be any way worst than non-G
has root, so it solves most of the problem
but cant flash any custom roms at the moment
non-G
using the exynos and mali-400 gpu
lesser games that support the mali-400 graphics chip, dont ask why, its too technical
unless devs start supporting it, its hard for certain games, nevertheless more games are being ported
G version is the first to come out, so it has tons of custom roms/kernal tweaks, if you're not a fan of them, then it wont bother you.
any questions just ask
