Yes, yet, I think Leonard Cohen is better.
My collection of Bob Dylan covers is even more extensive than Dylan originals. I’m hard pressed to find a cover version of a Dylan song that I don’t like.
Same with Leonard Cohen. Both great American songwriters. But I think Cohen is more of a New York thing.
I would not use better; the songs are so different. I cannot image Dylan writing Famous Blue Raincoat, Chelsea Hotel, I'm Your Man, Marianne, Suzanne, Bird on a Wire, Halleluyah ... nor Cohen writing any of Dylan's many, many gems; different trees in the forest of our dreams.
