You do pay a premium for the name but, as Colombo said, it's never that simple. I don't own any Savinellis but I do own a dozen or so Petersons of various grades and a couple of Stanwells. My worst smoking Dunhill outsmokes all of them except one Danish Stanwell that has always been an exceptional smoker.
IMO Dunhill makes the classic pipe shapes better than anyone, and the chances of getting a lemon are as near to zero as you can get. Their reputation goes back a century and is very well earned. They aren't for everybody, and they aren't a necessity, but they are more than just a name to show off.
Some of the best Danish Stanwells are among the best factory pipes ever made by any maker, from any era.
Like you, I have a couple of them, and they are superlative smokers.
I was very sad when they closed that shop years ago.
