I love spicy food. But I believe any of those sauces would make me feel a bit of spicyness.
I eat almost everyday spicy food or regular food mixed with spicy sauces I have, and the least hot is 100000 scoville. Lower than that I don't want to waste my time.
I bought this one in my last trip to Japan, only 105k scoville though but it's tasty:
This one I bought in Spain (670k scoville). Also really tasty:
And my favourite until now, a portuguese sauce which claims to be 400k scoville, but I would assure it is close to 1m due to the concentration and intensity:
I've tried dozens of sauces from different countries but nothing really really spicy. I even tried carolina reaper pepper directly and that was spicy, but tasteless.
I also have spicy honey, potato chips, peanuts and dark chocolate.
I have a specialized in spicy products store in my city, so I visit it at least once a month to get some stuff, it's fun and the owner is very friendly :). It's so pity I don't like beer, because the store has a few as well.
