For me, it is hands down, N. tripepii. Whenever I feed her or work in her enclosure, my nose and throat start to burn. It is like mild pepper spray. It is almost instant as well. I can see how this would prove an effective deterrent to natural predators in the wild.
I'm lucky, because I'm not too sensitive to urticating bristles, but N. tripepii packs a punch!
I cannot answer your question directly because, for the time being, I have no tarantulas. And, since I'm currently in western Canada (North America) I am literally on the other side of the planet, so my experiences may not necessarily apply in S.A.. (For instance, does anyone have any of these species?) But, in the arachnoculture hobby at large, the members of the genus
Theraphosa are generally agreed to possess the absolute worst urticating bristles with
T. apophysis (pinkfoot goliath tarantula) topping that very elite list.
Here's a photo of a spiderling displaying the reason for the name:

Be careful when dealing with these. They do not have a particularly bad temperament, or a particularly terrible bite in spite of their immense size. But man, can you suffer from those bristles! However, since your allergic/immune system is different from everybody else's, your mileage may vary.
