Best crossfire Region

Hello,
I would like to ask which is the best crossfire in terms of easy purchase of GP weapons and more good chances of getting better weapons in GP crates or GP blackmarket..
Also in terms of getting rare weapons easily when playing biohazard(zombie mode)
(EU NA PH ARX TW RU CH)?
I'm interested in a region that offers a capsule GP for a machine gun.
Because CF NA has it but its hard to win any, and CF EU hasnt got the capsule for MG.
Most importantly is the gp capsules weapons offer and In item shop GP..

CFNA is the best version unless you can read chinese.

Have you tried them all..
So crossfire NA has the best offering when it comes to GP item shop??
I mean is it possible to buy thompson,gatling,L86 or any cool MG in GP item shop.
Because CF EU sucks in this category also CF NA..
Many good weapons are in RP.
Some good weapons with knife addons as well.
Or M4A1 bronze. Or even melee weapons that are temporary in GP any crossfire that contains a permenant melee weapons ??
Please give reasons not opinions.
