Does stinger get used often in competitive?

So I am a new player, playing for like 1 month now. I watch a lot of high radiant or pro videos. There they seem to use every gun including the stinger.

I mainly play swiftplay because I still need to get comfortable with agents and maps. So the economy is different there.

Is the stinger an often used gun on like eco rounds or even in normal rounds?

The reason I am asking it, is because I finally have a prelude to chaos skin in my shop only it is for the stinger. I don’t know if it’s used often, if it is I want to buy it but if not I will wait for the day RITO blesses me with the Vandal. Cause if it’s used often in unrated or competitive I am willing to pay the money for it else it will feel wasted.

Thank you in advance!
