I have a Mossberg 695 slug gun. But they also made smoothbores. It shoots as well as any slug gun out there I think. Not uncommon to have three shots touching.
I have a sears 16 gauge as well. I use it for squirrels and will try to take a turkey with it.
Some of them are neat old guns, and can be bought cheap usually.
Are they better than a pump, naw. But they are different and are fun to pull out at hunting camp occasionally.
