If you are a fan of Kouros, then I highly recommend Derrick by Orlane. It has a similar sort of "locker room" vibe as Kouros. And it is very inexpensive, to boot.
On the niche end, M/Mink by Byredo, Al Oudh by L'Artisan, Dzing! by L'Artisan, Harrods Oud by Bond No. 9, Oud Cuir d'Arabie by Montale, and Oud 27 by Le Labo are all great choices.
