Which piano quality is the best, Japanese Kawaii KU-S 1 Second Generation (85th Anniversary Edition) or German Bernstein IBS 120D? thank you

I suggest you buy Bernstein! Two reasons:

1, Bernstein was developed by German Bernstein Company, and Sanyi Company was the agent for acquisition and sales. Both material selection and feel timbre are made according to German standards. Kawaii is made in China, and the piano itself is made in China except for Japanese brands, which are all produced by the boss in Perth, Hubei and Shanghai. The timbre is thin and light.

2. Bernstein's piano price is much better than the brand Kawaii.
