Bread flour is high gluten flour. Now it depends on how high is high
and of what function. Which flour to use is determined by what you
desire to bake. For most everything folks bake at home ordinary AP
flour works fine and so do the various brands. Flour is not an exact
product (they're actually blends to obtain a particular gluten value),
every wheat harvest is different... it's very easy to convince oneself
psychologically that one brand of flour is better than another... it
never ceases to amaze me how people can be made to believe that a
basic staple foodstuff is better because it costs more, is in a
fancier package, it's more difficult to locate... this is all called
"marketing".
