I believe the quality of pattern welded barrels should be assessed based on the
overall quality of the gun.
Well made Twist, Laminated Steel or Crolle Damascus have very similar strength based on the 1891 Birmingham Proof House Trial. Low grade Belgian imports, and the lower grade guns by U.S. makers for the most part had Twist, which was less expensive per 'rough forged tube'. And please be aware your "Fine London Twist" was almost sure to have been made in Belgium.
Judging the attractiveness of the pattern is entirely subjective.
