Which Brahms symphony cycle to choose

I have 2 cycles, Abbado/BPO and Haitink/RCO, and I'm trying to buy another one because I love the pieces so much. I have come down to Chailly and Dohnanyi/Cleveland. I've heard the former and I know I love it; the later has terrific reviews but I can't find sample so I don't know if I will like it, although I do love the conductor and orchestra so I probably will have a pleasant surprise with that route. Which one should I choose? Have you heard both? How do they compare?
