I don't intend to handle my T's (note I used plural ) a whole lot, if at all. That last thing I want is dropping it by accident, and worse yet, in the moment of freaking out I step on it!Brachypelma aren't typically spiders that will "bolt."
That said, they aren't spiders that I would handle, my emilia, smithi and vagans all kick hairs regularly. The emilia and smithi kick at the slightest disturbance, and the vagans aren't afraid to throw up threat displays either.
Beautiful spiders though, so if one (or more) Brachypelma species interest you, get one, you just may not want to handle it.
Out of the 3 you listed (boehmei, emilia and smithi) they are all going to be likely to kick hairs, so go for the one you like best in terms of looks.
It's a tide between boehmei and emilia.
