Now, I'm really late. SMGs are the dominant weapon in BO2, but then the top OP ones like MSMC and PDW got nerferd back in 2012/13 lol. I was wondering if they're still better than ARs, since I haven't found anything saying SMGs are still better than ARs after the patch. All I've noticed after the patch was a little extra kick to SMGs.
Really late to this. This is an overall tricky question seeing as both categories have strong contenders even after buffs/debuffs.
ARs- FAL, AN94, M8A1
SMGs- MSMC, Skorpion EVO, Peacekeeper
Honestly in my personal opinion i feel they are tied 3-3. All depends on what gametypes you play and what your preferred playstyle is.
Since I'm and SnD player and prefer mid-long range battles I go AR
