Agreed on this one, however, he can get sample sizes, which will not kill a paycheck, to try out. I like Private Blends from Tom Ford and Andy Taurer has a few good ones. But go to https://www.basenotes.net for opinions from fragrance nuts. I find that a guy may enjoy the notes more than the self absorbed women around him. I'm ashamed to also know that age, setting, and seasons will be a factor in choice. Honestly, focus on personality, paycheck, and washing your nuts as an alternative.
