Given your stats, neither one of them are an especially good choice. However I'll try my best to
help you out on this one.
Shotguns
Pros
- I don't know this for a fact, but the Wiki states that shotguns fire shards of shrapnel out
when they're used. It may be possible that shotguns are capable of damaging more
than one target at a time.
- They all have average accuracy, which is great for someone with low accuracy stats.
- Most of the shotguns have a max damage of 4x9 per shot, but what changes is their
ammo capacity, which effectively alters how much damage they can dish out. The
USAS has a 20 clip, 4x9=32 x20 = 640, couple that with Fast firing speed and you've
got a force to be reckoned with.
- Perfect for Main Gate or Junkyard in the OA
Cons
- Despite the above I still have to mention the zero critical chance, and this is only
compounded by the fact that you have a lot of points invested in Critical as is.
- You have to place points in strength, which is typically useless unless you use
more than one piece of equipment that uses said strength, such as chainsaws and
higher tier armors.
- It seems a little unfair to make mention of the aggro this class of weapons creates,
considering all firearms of any kind gradually raise it. However I'll add it to the list.
- A secondary ammo type to take up space in your inventory.
Machine guns/Light
Pros
- use pistol ammo, which is quite abundant and easy to find.
- Large ammo capacities, which means extended periods of saturation power between reloads.
- Fast reloading.
- Low strength requirements.
- Low Critical Chance
- Great for Main Gate
Cons
- Pathetically weak
- Low accuracy
- Expensive & Wasteful
- Raises aggro faster than you can put zombies down.
- A secondary ammo type to take up space in your inventory.
Machine guns/Heavy
Pros
- use rifle rounds, which equals more damage
- Larger ammo capacities, which means extended periods of saturation power between reloads.
- Will use the same ammo as your Rifles, which means more inventory space.
- Great for Main Gate during OA
Cons
- Even poorer accuracy
- Diminished reloading speed
- Increased strength requirements.
- Insanely Expensive & Insanely Wasteful
- Diminished Critical Chance
Both weapon classes have their glaring flaws when coupled with your stats. but to me, the
worse class here is most certainly the machine guns. Low accuracy makes them both
wasteful and inefficient at killing zombies to make them worth it. However if you do
go with Machine gun, aim for the Heavy ones, their increased damage output makes
them better than the weaker light class.
