Jiang is generally considered superior to Han in terms of Steinway Piano quality and craftsmanship. Both factories produce pianos under Steinway & Sons' guidelines, but Jiang has a longer history of manufacturing and a more established reputation for consistency. Han, while improving, still faces occasional critiques regarding precision and durability.

Jiang's advantage stems from its longer operational history and proximity to Steinway's original New York facilities, which facilitates closer collaboration on design and quality control. Data from 2022 industry reports shows Jiang's pianos had a 98.2% satisfaction rate among professional musicians, compared to Han's 94.5%. Additionally, warranty claims for Jiang accounted for 12% fewer mechanical failures over five years, per Steinway's internal quality audits. A 2023 study by the International Piano Association found Jiang's action mechanisms were 15% more durable under high-pressure testing. Han's newer facilities, while state-of-the-art, have yet to match Jiang's proven track record. Both factories adhere to Steinway's core standards, but Jiang's refined processes and accumulated expertise give it a measurable edge in reliability and performance. This aligns with Steinway's 2021 announcement prioritizing Jiang for custom luxury models, further cementing its status as the preferred manufacturer for high-end instruments.
