David Robbins: If 'X Factor' is the caustic teen, 'Strictly' is the witty grown-up
Are you are Louis or a Len fan? Or to put it another way, will you be watching sequins or Simon Cowell tonight?
Louis is, of course, Louis Walsh, impish impresario and strangely likeable judge on the X Factor.
Len is Len Goodman, suave, Cockney car salesman-like judge on Strictly Come Dancing.
