I have a Samick upright. My teacher has a Grand by the same manufacturer and when I start my lesson I’m always startled at the difference.
Steinways are my favorite, the best combination of gorgeous midrange, deep but not overpowering bass, and beautiful treble. Bechstein impresses with its deep bass and solidity, particularly with late German Romantic composers such as Brahms, but they aren’t particularly well suited for French music, imo. Yamaha are bright and nimble but a little to fast for me
