First: Welcome to the Basenotes
Second: Don't look for common notes, this case confuses you without good results, many fragrances use Citrus(Bergamot, Mandarin Orange, Lime,...), Vetyver, Lavander,... in their structure. Instead, look for differences and intensity points. For example Dunhill Edition is an Aromatic Fougere, So Lavander should be one of the dominant notes. Clinique Happy is Citrus, and many fragrances have citrus, But in Happy it's dominant.
In my opinion, You will like Opium Pour Homme, Must De Cartier, Rochas Man, Burberry London.
