There is a huge gap between how Chopin wanted his music to be played and how they are actually played by most subsequent performers.
First, Chopin did not at all consider his music a part of the Romanticist movement. Second, his application of rubato was much more conservative than commonly believed; he hated misplaced lingering and dragging. Third, he rarely made his students learn his own music, insteading focusing primarily on Mozart and Bach.
I believe the way Chopin played his own music would sound much more "classical" to the modern ear.
He wrote some brilliant things every now and then in his smaller works. But most of the larger works are transcendent, like the ballades, polonaise-fantasie, the concerti, and the sonatas.
But the problem I have with Chopin is that when new learners hear Chopin, they are so naturally drawn to the Romantic sound that they expect all piano music to sound like Chopin. That, unfortunately, often leads them to dislike Bach, Mozart, and the like.
