I think ghost pepper is fine and can add a unique flavor but it's really quantity dependent

for me the perfect level of spicy is at the level of a hot paprika, like how I've been making the cajun food for work. I get that feeling of warmth, a lot of smoky pepper flavor, and I can always make it a little spicier with some cayenne. I get good enough reviews from my Turkish and Mexican coworkers and I think if I made it any spicier a majority of people would just refuse to eat it lol
