Difficult question. I'd say they are equally strong.
My personal opinion: Antaeus is more subtle, though very strong, Trussardi smells like the stuff you spray on your carpet to keep your kitten from peeing there. Trussardi isn't my cup of tea. I like Antaeus better, it lasts an eternity on my skin but does not get overpowering, Trussardi lasts an eternity as well but I don't like it anyway.
