From what I hear White Tomesol is a must grow and maybe one of the best.
Apple ask Blane or Darth for some seed of White Tomesol. Here is a pic
I have only grown Coeur de Boeuf Blanc myself, and Snow White, a cherry. They were both pretty good, the cherry was good and sweet, CDBB was a big heart paste. This year I will be growing one called Weapons of Mass Destruction (white sport). You will not find this anywhere though so don't look.
Not a huge fan of whites myself.
If you would like some seed Pm me smallgardener.
I can't give out any WOMD (white sport) though. This is still a work in progress actually just found last year.
