Whilst I would concur that most twin flying is for training and not for fun, it depends upon the mission. Longer over water sectors (U.K. - Netherlands/Denmark/Ireland etc) are more appealing in a twin. Remote areas too are better served in a twin, it gives you more options.
Agree that the higher performing singles (SR22/C400 etc) are just as fast and tend to have better avionics / comfort /appeal and have generally lower operating costs which has led to the decline of the light twin.
