For $90 the stock UMA R-9 offers the best protection.
Second would be the R2C IR-81.
Lastly the Sabas Pro Series. I rank Sabas third because the padding is thin when compared to both the R9 and IR81, BUT Sabas beats both of them in back padding by a wide margin considering both the R9 and IR81 have no back padding at all.
That being said the Sabas offers a lot of protection for the face, im not trying to say its bad because its not at all its just the other two protect the face and nose better due to thicker padding and because the cheeks hug the face and cover up more.
It comes down to what you value more, Face vs Back of the head.
The Sabas is good all around. And the R9 and IR81 are good for the face.
If i ranked my favorite headgears of all time it would probably go.

If price matters, i think the Sabas is $80 right now on sale. After that a stock R9 is $90, the IR81 is $100.
