If you like speed, definitely doubles especially mens. Singles is more about stamina and perseverance.
Men's doubles for a display of power and speed. Men's singles for watching more appreciation over the construction of a point as well as the retrieval skills by all the players. Deception is also much more fun to watch in this event if you like and appreciate that sort of thing. Women's singles is the slowest pace of all the events, probably the least exciting from a power and speed standpoint. But it also requires the most tactical awareness because power smashes is not nearly as useful in women's singles than it is in men's doubles. They have to really get their opponent out of position to win a point.
I likeSingles personally cos I find the doubles partner is very impt,if cant coordinate well it's very very messy
I enjoy watching doubles more for the speed and power and intensity of each rally. But you have to appreciate the skill and the placement of the shuttle from the singles players. Mixed is my favourite though, fast rallies with the intention of pushing the opponents into a weak position
More exciting is always doubles because they are played at a faster pace. However if n only if u have a fixed partner who understand how you play. Otherwise it might be frustrating.
