Depends on what you like. They are completely different kind of fragrances. If you want something safe, then go with D&G. If you want to be a bit daring, then go with NR. I would pick NR. But the chances of someone not liking NR are much higher than not liking D&G. By te same token, then chances of someone falling in love with NR are much higher than falling in love with D&G as well.
fresh & subtle = D&G
not so fresh earthy & not so subtle = NR.
I find that a lot of people are asking for Narciso Rodriguez at fragrance counters lately; IMO neither is very "exclusive," but since you are in Chile and the weather there is pretty cold at night, I'd go with NR for evenings. If you're looking for something for every day then the D&G would be better.
