My ranking would probably vary from week to week but here goes:
14 Foxtrot - the most elegant - always my favourite, no matter how the other dances vary in my rankings
13 Quickstep - love it (big adrenaline rush dancing it)
12 Rumba - beautiful but not the strictly version
11 Argentine Tango - find this difficult to compare with others
10 Waltz - can get a bit boring though
9 Tango - Prefer AT now I've started dancing it
8= Jive - love to watch, but don't like dancing
8 =Samba - love to dance - not so keen watching
6 Viennese Waltz - but only when done properly to grand viennese music. Then it is exciting and romantic. Otherwise dull
5 Cha Cha Cha - really like this when danced by pros but otherwise lukewarm
3 American Smooth - too much of a mish mash for me although love Astaire and Rogers
2 Salsa - not really a club dancer
1 Charleston - just don't get it
