Issey Miyake is inoffensive, and not good if you want to make a statement. It has its bitter bits but other than that is an excellent fragrance to be wearing if you don't want to make a splash but want to smell nice.
I haven't smelled Halston Unbound.
Perry Ellis 360 Red has some essential differences from Acqua di Gio, but I think overall it's weaker because of the quality of materials.
I absolutely love Versace Blue Jeans. It's almost my daily sweet-and-spicy fragrance of choice. Smells nice. Lasts long. Cheap.
