Though
@BigBossBigTeef must know better anyway.
I know what better?
Are we talking about the video game or medically?
Video game wise, chest is always the best option when it comes to hardcore shooters because the hitbox is bigger, easier to see and focus on. Especially in games like Insurgency, Arma, or Red orchestra where people typically die very easily.
Headshots should only be considered if the body is obscured. When it comes to hardcore shooters, skill does play a role but spacial awareness, logic, and patience will beat twitchers most of the time. Because you can't always predict enemy positions, and hiding is the best way to play these type of games.
MB2 is a hardcore shooter but it uses an arcade esq health system, headshots are more ideal in MB2 because there are classes that can tank a few chest shots before dying and the game doesn't have the fighting game mechanic of staggering while getting hit. When your character gets punched, your character doesn't animate response blows. You keep the normal standing position until death.
This universal for all the classes, people don't animate to blows, they just suffer knock back.
One of the big problems that gunners face the melee force class is not just thier force powers, but that they don't animate blows. They can keep swinging while getting shot, the jedi can tank a blaster shot to the chest mid swing and keep the swing animation going.
In 1.4 they introduced the fighting game mechanic of staggers which they dub as flinching. Where if a gunner hits a jedi while he is swinging his saber. The jedi will stop the swing. However this only applies to the jedi/sith class. If flinching were applied universally, we would loose the arcade esq element which I think would be interesting. But would need testing to see if that would actually be fun.
Medically speaking, you can just google this kind of information.
What Are the Odds of Surviving a Gunshot Wound to the Head?
Only 5% survive gunshot wounds to head

Theres science and papers behind everything with favor or opposing views. Honestly headshots have a lower chance of survival because replacing what was damaged is very minuscule compared to the body.
The body, most of the organs can be replaced via transplant surgeries.
This kind of discussion is a gateway to stim cell discussion and then devolves into ethics about such usage.

Blood loss is the typical lead factor into people dying from any kind of gun shots.
You can google "exit wound" and then look into what caused the wound.
Gun shot related deaths also depend on what kind of ammo was used, and how fast first aid was applied.
From my personal experience in hospitals, headshots only seem to happen in children when it came to gang violence while adult victims typically suffer more stabbings, beatings, and chest shot injuries in comparison. There is probably a reason behind that but I haven't lived in the hood since I was like 10, and haven't really looked into it. I could guess why that is. Maybe it has something to do with children typically having big heads until their teens. Other than that I don't really want to google people getting shot, maybe for those interested in law enforcement would find this more interesting than a medical student. I know why people are killed, I don't want to know how.
