My father's worn British Sterling for 30 years or more, and I'm looking to offer him a better alternative, or at least an alternative at all. It's all he's ever bought. Any suggestions? Similar notes/accords?

He's a successful businessman/academic, semi-retired, in his 70s, outgoing, outspoken and good-natured. He's always worn the aftershave.

I'm thinking about Guerlain's Vetiver, Davidoff Zino, or even Bulgari PH as an all-arounder (though I can't find that in an aftershave), as a quality alternative. Any suggestions? I'm having a hard time pinning down something that might smell enough like BS (heh!), but more 'refined', that he'd give a try.

TIA for your suggestions.
