I've only ever come across unscented antiperspirants. Most deodorants I tried of the stick variety, with a few exceptions, didn't have very long lasting scents worth worrying about. Similar with cheap body washes and with average shampoos. Unless you are using very smelly stuff, any fragrance you wear will easily overpower the light scents of the other products you use - you won't notice any clashing. The only clashing issue I've had is with strongly scented spray antiperspirants.
