Do i get a Mk12 Mod0 or Mod1?

Soooo i was thinking of getting a Double Bell Mk12 Mod0 replica, but just discovered that they also have a replica of the Mod1, so now i don't know which one to get (I know the Mod1 has a quad rail and is a bit lighter, but i'm still not sure).

Any help is appreciated, i'm extremely indecisive.
