when you loft, assuming you have construction history on, you can change the way the NURBS conversion went if you told the loft to do the conversion to polygons as well

in the channel box you can change the attributes of the nurbsTessellate node that pops up after converting to polygons

play with the Format,
make the polygon type quads

and if your are using the general format then the U Number and V Number can increase the number of polygons (control click both and middle mouse drag to change them both at the same time)

remember, polygons can never copy NURBS exactly because edges are always going to be straight.
