I don't own a Dunhill nor a Castello, never have. I feel I get excellent use out of other English and Italian pipes, and in the case of my Ser Jacopo and Ferndown, I may be getting the same or better. I'm also embarrassed by the high quality of smoking I've had with old workhorse factory pipes when things go right. I feel I do well with Nordings, most brands of French pipes, and various U.S. briars that now sell for almost nothing. Castello makes a beautiful pipe, and they make them in all sizes, but the U.S. marketing pushes the big heavy ones that cost half again as much.
I have collected and smoked many quality pipes, (I worked in several pipe shops in the 70s) to include Dunhill and their second Parker, Charatan, Comoy, Astley, Freiburg & Treyer, GBD (both English and French made), Barling, and a number of Benchmades. I have a variety of Danish to including Prebenholm, Soren, Benwade, WO Larsen and Nording. On the Italian front, Castello, Caminetto, and Savinelli. Of all my pipes, Savinelli (including Autographs) are my least sweet smoking. Among my Dunhills, Parkers, Charatans, GBD, Castello, Caminetto - even a $4.00 Amphora X-tra I got in college - I have what I call "magic pipes"; they are unbelievable sweet smoking. I call them magic pipes because, at times, I think there is no accounting for brand. Even among my Dunhills I have a Squat Bulldog 5108 Cumberland that beats all of my other Dunhills, hands down. My only American made pipe other than Benchmades, is a Bertram of DC prince that belonged to my father. It is a beautiful smoking pipe.
