Love is rather a strong word for a duvet!  The duvet I had was a 13.5 tog and I felt it was not warm enough so I bought the 15 tog from Wayfair.  It was not cheap but it is not filled with feathers [stuffing items or humans with feathers is barbaric, extremely cruel and unbelievably painful, so I have man-made fibres.  This duvet is warm and very comfortable and  I recommend it, especially as it is warm and also light which is an added bonus.
