I can comment on your Armani's and say I like Acqua Di Gio and Code as well. My only complaint on ADG is just the commonality of it, it has a nick name here of being "Acqua Di Conformity" because it is so popular. I can't fault the scent, I love it! I just wish it was not so popular with the high school and college crowd. I noticed Nordstroms was having a special on a huge bottles of ADG not too long ago, this stuff damn near comes in gallon drums now.
Code is very nice, my only complaint here is the scent life, it seems to willow and fade in under 3 hours. Sometimes to get around this I spray heavy but to do this with Code you will essentially have a 25 foot do not enter zone around you for about an hour.
Good choices, keep in mind the faults I pointed out are very common among colognes. I have stuff that costs 3-4 times more than what Code does that does not last any longer and even projects off the skin even less.
