What's better? (FA:S, TFA, CW 2.0 or M9K?)

If you need attachments - CW2.0 or FAS (TFA partially)
If you "I want everything at once" - M9K (for other weapon systems you need search packs (CW2.0 and FAS have stock weapons) )
TFA is most realistic weapon system in my opinion, but for attachments you need download additional addon + in CW2.0 and FAS you can manage attachments drop, but in TFA attachments drops after pick weapon

M9K is bettter, pleasant shooting, sound and models..
My friend also making server, he use M9K

on my opinion m9k the best but you can try C.W 2 for you server

The best is M9K, or SWBASE decide for myself M9K and CSS weapons

CW 2.0 is better in few aspects.
They don't lag.
Most of the addons on the workshop support this addon.
They are generally the best.

Cw 2.0 is better, this is best weapon it has great shoot sounds and not bad damage!

I use CW2.0 on my RP server just because of the customizability.

I think TFA, it is more beautiful, almost all weapons are made for it, and yet a cool pack, as for me.

I use M9K for my server. M9k is quite old but still acceptable. it is also user friendly as the weapons are easy to use

I think TFA, a very large selection of weapons, many where supported, well, as for me, the best choice
