2x2's are a bit easier than a 3x3!
2x2's are many peoples second-to-go cube to solve.(Not mine by the way, mine was megaminx)
2x2 is a very hard event to master because of the world records that are under one second!
2x2 is also a very fast event.(most of the time, unless their are people in your compition that solve 2x2's in 1 minute!)
