I'm not a huge fan of Russian Leather, but the best I can think of is Santa Maria Novella. The price is hefty but the performance is absolutely fabulous, as all SMN aftershaves. The scent strength is around 8/10 and the persistence is vey good, I never used cologne after applying it.
If you like mentholated aftershaves that sooth and calm the skin and price is not an issue, that's the one for you!
I hope that helped! Cheers!
