I can not see any points in common with OS. This is harsher, brazer, pungent, while ChpM is subtler and restrained. OS is spicy, ChpM is not. I like them both, but they are worlds apart. Are you sure did not get a counterfited version of ChpM?
Take in mind ChpM is a scent designed in the 1950's, a time when fragrances for men were made to be "weak" in actual terms, strength being reserved for scents to be worn by women, since these were supposed to be noticed by those around the wearer, while men were not supposed to smell at all.
Comparing ChpM with Antaeus is, to some extent, a futile exercise since Antaeus reflects a style in vogue during the 1980's, a time when the more men smell of perfume was considered good.
