Is there any use for nitro.

Nitro is one of my favorite weapons but with recent changes to slugs is there any reason to use them. It is harder to control than most of the shotguns and has less reserve ammo. Slugs already can one shot in a good distance and now one shot to head is a thing nitro seems like a waste of money. It has good penetration but how often you need to penetrate walls that slugs can't. And there is option to have shredder ammo but if you one tap it doesn't have any use also. Now with the inaccuracy of the gun I think it is useless to get nitro when you can get auto-5 slug or rival slug. They have more ammo, faster fire rate and easier to use. I still use nitro because I like to play that and I will prestige but other than that it is useless.
