It's an easy call for me as I love D&G and detest Dreamer.
D&G is quite similar to Tabarome, but has more of a sharp citrus top note. It's slightly sweeter as well. It has more pepper and no ginger.
Where to start with Dreamer? Initially it is a nice smooth scent, but after about 30 minutes an overpowering aniseed note comes along that obliterates everything else.
