The best revolver ever...
I am no friend of absolutes, particularly statements about the absolute best gun. Your definition simply might be different than mine.
There are a few revolvers of outstanding quality; the Korths from 24 series on, the Manurhin MR73, the Freedom Arms Casull revolvers (83?), S&W registered Magnums, the triple locks and hand ejectors, as well as the early Pythons ( until the late 1970s). The German Reichsrevolvers were well made, too. What about early Colt SAA's?
There a many excellent revolvers that are great shooters, though the build quality is not up to the above mentioned but it has little bearing on practical purposes.
I can shoot my S&W K-22 and M14-2 every bit as well as my 1972 vintage Python or any of my Korths. Nevertheless, we are all human and I have this 24 series rimfire Korth that I love to shoot in D/A more than any other revolver. It is my "best" and dearest gun, next to a cheap LE trade in S&W 65.
And still it may not be the best for you. Heck, it is just an overpriced German .22 ...
