Prepare for painting with sugar soap or fine sandpaper?

I want to use white gloss to paint some white doors inside the house.
The doors were painted with white about 15 years old and are getting
discoloured.
I know preparation is important but in this case I have to compromise!
I'll use white undercoat and one topcoat of gloss. The undercoat is to
even out the surface and prevent discoloured patches showing through.
QUESTION: If I can use either sugar soap or fine sandpaper to prepare
the surface (plus filler for holes) then is it better to use fine
sandpaper than sugar soap?
Even a five minute rub down with fine sandpaper makes a big difference.
Use as much undercoat as you need to hide the imperfections, then one
thin coat of gloss
