I played the Busoni transcription of the Chaconne and LOVED it. I also like the c minor partita a lot. But I like Bach a lot in general, so I don't know if that's what you're looking for.
I'm also a "romantician" in first place, but my favourite from Bach is probably the "little fugue in G": https://www.sheetmusicarchive.net/dlpage_new.cfm?composition_id=1014
Interestingly, I'm in the opposite position.I've always loved and appreciated the depth and complexity--both intellectual and emotional--of Bach's music. I also liked Mozart and other early music, but my teacher said I needed to start learning some Rachmaninoff, Ravel, Debussy, Beethoven, Liszt, etc.It took me a little while to even learn to appreciate rach 3.
I wish I were more drawn to Bach..Maybe it would help if I were a religious person..
