I'm not at all keen on the rumba- it's often so embarassing, I find.
In Ballroom, I get most excited about the Quickstep and the Viennese Waltz, and in Latin I love the jive. I also look forward to the tango and the Argentine tango. In the non-Strictly dances, in things like Strictly Dance Fever, I really love the jive-based ones like the jitterbug, the lindy hop, and the charleston, but I think that's partly because the music appeals to me most.
