I'm pretty easy going when it comes to scents and have many favourites so it's hard to nail it down to just one, but if I could pick something that really stands out for me it would be a tie between Domenico Caraceni 1913 (RIP) and Czech & Speake 88.

As for the worst, I have to agree with the others: Clubman Lilac Vegetal. One of the few scents I found genuinely unpleasant and my wife had an instant allergic reaction to it. Needless to say, I'm glad I was able to sample it before buying lol
