Asafetida. People call it horrible unless cooked but imho it just smells like garlic++. It's sulfurous, but so is garlic and a lot of food really. Sulfur isn't necessarily an unpleasant smell to me. As far as I can tell the smell of asafetida doesn't change when cooking, it just gets milder.
Healthy compost also smells kinda nice, rotting meat is awful but if you're not getting putricene and co from anerobic nitrogen decomp decay mostly smells damp and warm and spicy.
Durian also smells amazing, but that's a pretty popular opinion given the wild popularity of the fruit. Potentially more sulfur not aversive stuff there.
In the hate camp peanut butter. It is overpowering and early in the day makes me throw up. My wife adds it to coffee sometimes which makes the entire house smell of peanut butter for hours. It's a very powerful and cloying smell.
