Why Do Oud-Based Fragrances Feel More Luxurious Than Regular Perfumes?

I never realized how important scent depth and longevity were until I started comparing traditional perfumes with richer Middle Eastern fragrance styles.
A lot of perfume enthusiasts seem drawn toward oud perfume fragrance collections because of their strong woody character, long-lasting performance, and unique scent evolution throughout the day.
For those who enjoy premium or niche fragrances:

• What makes oud stand out compared to floral or fresh perfumes?
  
• Do you think oud works better in colder weather or year-round?
  
• Which fragrance combinations with oud do you personally prefer?
  
• Are niche perfume houses producing better oud scents than designer brands?
  

Would be interested to hear recommendations and experiences from others who enjoy deeper and more intense fragrances.
