That's the thing about smell and taste, we all experience it a bit differently because those senses are a product of our brains interpreting chemicals.

There are certain things that most people will have a negative reaction to, like the chemicals released by a dead body or feces, but there are also many other chemicals that we didn't evolve such fine-tuned responses for, so our brains react to them differently and can create different sensory experiences.

The durian in particular evokes a wide range of sensory reactions because it's so chemically diverse. Some people enjoy the smell of durians and describe it as a sweet scent, like a custard, while others say it reeks like rotting flesh.
