I suppose to answer the OP, Gain is pretty much P&G's perfume bomb. Some people like it, but anyone who prefers a more neutral odor is probably not going to like it. I prefer using detergents without perfumes, but standard Tide and Cheer (now a bargain brand) don't leave much perfume once it's rinsed out.
Oh, there's also Gain dishwashing liquid. I don't think it's much different than Dawn, but it does smell like regular Gain. However, I don't get it since everything just washes off anyways.
