[Star Wars] What kind of protection does a Stormtrooper armor offer against blaster fire?

Whenever a stormtrooper gets shot by a blaster, they just fall down and appear to be dead. But are they dead for real?

I recently saw Kenobi's 5th episode. In it, Tala >!gets shot and without any armor, stays a live for a while. In fact, she doesn't die from the blaster shot, but dies as a result of the explosion that she herself initiates.!<

So, if the armor doesn't help against blaster shots, what's the purpose? Just as a uniform? But I guess the Empire could save quite a lot of credits by using some cheaper non-armor uniforms.

Stormtrooper armor is designed to absorb or deflect glancing blaster bolts. It is relatively useless against slugthrowers, piercing weapons like arrows or spears, and offered little protection against concussive weapons such as clubs.   


Ultimately the armor served to anonymize the stormtrooper. The Empire relied on overwhelming numbers of faceless troops to maintain order. If one stormtrooper fell, two more would step in.
