From Diptyque, I like Patchouli, John Galliano, and Cypress. I currently have Eucalyptus, but need more time with it. A couple others seemed weak, although I haven't tried that many.
Sahara Spice is my first Nest candle and it's outstanding. I recently finished Wood Sage & Sea Salt by Jo Malone and I'd get it again.
I'm using up my candles so I can buy some new ones. One of my favorites for spring is Bob's Flower Shop but I forget the name of the maker.
