Logos for 2016 Olympics

What is your favourite logo for the 2016 Olympics? Mine are Madrid and Tokyo. I don't like Rio's at all. Not even Olympic colours, looks like its for an organic food.

I'm Partial but I like Chicago's and Tokyo's

Chicago had a good one before this one that resembled a torch with the flame being the skyline and the torch base being the Reflection in Lake Michigan

I agree with canuck...the first logo of Chicago was the best one. Among the others the best are those of Baku and Doha, the Chicago actual logo it's a little banal and without references to the Olympiads, the knot strangled knot of Tokio is essential, introduces all 5 the colors and among all it's the most Olympic. The Madrid one has some beautiful colors, the open hand has a rich symbol, but in certain cultures it doesn't have a positive value and it seems more proper for some humanitarian association.
