I would say its better purely because the guy behind the BR mod now has it as his own fully fledged title, replete with all the development and continued expanding that a full title has over a mod.
This basically.
We have a community that has played Arma 2 through to Arma 3 and pretty much all the mods since dayz vanilla.... BR was a favourite..... They've also played H1Z1 BR and have since played this.... The complete consensus is that Battle Grounds is the boy, basically arma 3 BR without the arma bugs meet Counter strike. Which judging by the gun play is not far off an accurate description.
