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

I use FAS2 myself, but M9K pack is the best, I hope it helped)

If you wanna make REALISTIC weapon, then use CW 2.0. If you are making StarWars RP server, then use TFA.

Answering the question briefly? TFA
why? Because it is easy to use and edit, there is a lot of it and with good quality textures, it is also nice that some of them can also be easily edited in the game (add-ons etc.), so in short I recommend it

I prefer TFA because it's simple and easy to use, but yeah

I use m9k and i would recommend you the m9k its really good for some good things and really fun to use and doesnt create lots of errors or lag

TFA. It feels a lot smoother than FA:S, CW, and def a lot better than M9K. As much as I love TFA having to download the individual weapons, is a real pain, so that's one advantage CW has.

TFA Base one of the greatest optimised base u should do a gmod server with that base mate

I recommend the M9K, because it has a lot more weapons and you can make more commercial guns from the gunsmith.

M9k is simple to setup, but really restricts playstyles for each weapon. That's why I suggest cw2, you can sell weapon and attachments so players can use weapons how ever they feel. Assassin with a scoped, silenced pistol, done. Cops needing to up their guns but don't have the money for a rifle, load some stronger rounds into the gun.
