I love the harsh opening of Santos, and then a little after that as it warms up, but I find it loses a lot of its character in the drydown. Because of this I cannot fully recommend it though.
Body Kouros is a pretty good scent. I smelled it on someone else last time, and it did a good job of having monster sillage distance wise but not being too heavy. This scent isn't amazing or anything but it's certainly good.
Antaeus is the best of the three you are considering, hands down. The opening is really odd, as it almost smells like a feminine scent, but it quickly settles down into a beautiful masculine scent. I find this one to be quite difficult to describe, but you should defintaely try it.
