Deodorants help control body odor, while antiperspirants also reduce perspiration; scented body waters provide fragrance and should not be assumed to offer either effect. Sticks, creams and sprays differ in how they are applied and how they feel on the skin. Choose first by the effect you need, then by application format and scent; if your skin reacts easily, check the ingredients and stated suitability rather than relying on the format alone.
