spas 12 or xm1014

Hello CrossFire community,

Tomorrow I'm going to make a shotgunner!
I have seen many shotgun montages but I can't still choose between them.

I'm not going to buy any ZP or GP crates because I have no luck with it.

So my question again:
What shotgun is better... XM1014 or SPAS-12?

If you have any tips for shotgunning please say, they are always welcome
