I own the following :
Bianchi road - still use it here and there for races and quiet roads ( eg. suikerbos )
Norco full susp. - MTB stage rides and rough gravel roads ( eg. Breedts nek pass )
Momsen - smooth gravel or road shoulder ( eg. Brits canals )
Pretty much balanced and spoilt for choice, I would still like a hardtail too though.
If I had to choose 1.............definately the Momsen Gravel !
