- Varvatos Vintage
- Terre d'Hermes Parfum
- Hanae Mori HM, which I'd keep for wearing on dates.
- Dior Homme Sport, which I'd keep for summer days.
I'm not saying these are 5/5. I'm saying, if I had to limit my entire collection to just a few scents - all designers - these would probably be my picks. When limiting a collection, I think it's wise to think about your needs. Work? Dates? Weekends? Summer? Winter? Formal? Casual? ...? Think about all of the things you do, and make sure you've got your bases covered.
Since you said you're looking to drastically cut back your collection, here's my advice: Tonight, take every single bottle you own and put them all away in a big box. Tomorrow, pick one to pull out of the box to wear, and put it where you currently keep your favorite scents. Which did you pick? Each day, remove another from the box to wear, but ONLY if you need it more than one you've already pulled out of the box. And if you change your mind about one you pulled out previously, put it back in the box. After a while, you'll end up with a small collection of scents you get a lot of use out of, and you'll have a box of scents you don't need.
