the conical flask one is for synthetics ie will be 'gentler' and have a lower spin speed and a lower dryer temp.
the cloud is meant to be a cotton boll and will have a faster spin speed and a higher drying temp.
Remember the drying function of washer/dryers is notoriously shit though - you are better off using a clothes horse by the radiator. And even if you do use it never try and dry more than half a washload at a time.
The AA programme is the economy/ energy efficient one, but this is most likely because it uses cold water and/or a v low drying temp, so needs to run for longer to get the same amount of cleaning/drying done, iyswim - our dishwasher has similar.
