And it's really no fair to compare a general anyone-can-use-it feat like Toughness to an ultra-specialized feat like Honored Foe, which only works for a single class and then only if that class invests in a certain ability.
I've never taken any of the other ones (not even Improved Init).
I've seen several other people take Toughness, but I don't think I've done anything on the list except Improved Initiative, which I eventually retrained out. Lots of Weapon Proficiency and Weapon Focus, though.
