I rather enjoy most of them - but I wouldn't wear many of them in public. They are a bit heavy-handed, but very interesting.
Good thing you bought a discovery pack, rather than blind buying one and hating it. IMO, just getting to try different fragrances is worth the price of the samples.
If you are looking for some small niche fragrances that are more mallet than sledgehammer, you may want to look into Kerosene fragrances. Very nice, underrated fragrances, and he also offers a sample pack of all 9 fragrances.
