I do not like the look of black hardware on white cabinets so I would do stainless .

Black hardware will add contrast to your light kitchen, while stainless will tie in the appliances. What is your kitchen/home style? IMO, black tends to lean more modern. Without seeing photos, I don’t know what else is going on in the room, so it’s hard to give an informed answer.

I also think that black hardware is too harsh for white cabinets.
