It is similar to buying cars, Rolls Royce, Bentley, Aston Martin suits some.Others prefer Mercedes, BMW.
If my preferred gun was 12 guage SxS I would consider A.A.Brown, David Sinnerton, Peter Nelson for an individual bespoke gun.If I wanted a named gun it would only be Purdey or Holland.But if I could wait and have todays very best I would have a bespoke Greener.
Watson do make superb small bore guns and have the experience, knowledge, and raw materials to deliver early with a 28 or 20.
At the end of the day you pay your money and take your choice.
If it was an O/U I would have a Boss or Watson for kudos or a Belgian Browning for reliability.Boxlock would have to be a Tony White.
