Salt or Pepper, you choose

Pepper

in terms of enjoyment for foods? Pepper by far.
in terms of whats most important for human survival? salt.

Voted pepper.

Salt. It has many more culinary applications.

I can get special salt treated in garlic and moruga chili....at that point, wtf do I need pepper for?

Well you dont need to add more pepper to something containing chili peppers.

Pepper is faaaaaaaar more healthy.

Pepper.

Salty junk food and sweets tho.

As a condiment? Neither, assuming you mean black pepper and table salt, which I never use for anything.
Chilli peppers on the other hand, WAY different story. I love cayenne and habanero powder. Habanero and scotch bonnet sauces are my favourites, but I also love ghost and Carolina reaper sauces. As far as peppers to use in veggie dishes, I love Thai/Birdseye for heat and jalapeños for texture... mostly the thais because of high availability and cheaper prices.
