What makes one puzzle brand "better quality" than another?

The factors customers most often cite are piece thickness, tight interlocking fit, minimal cardboard dust, and matte versus glare-prone finishes. Ravensburger titles in this pool draw repeated praise from verified-purchase reviewers for snug fit and durable pieces, while several budget brands earn strong ratings but more mixed comments on dust and occasional fit looseness. Because no independent lab data is available for these specific titles, piece-quality claims here rest on customer reports rather than measured testing.
