just my personal opinion but the 3-5 rep range (or even max singles) can sometimes be used by a BBer to break through a plateau, in particular by providing that cns stimulation through heavier weight.
where I do think there is a difference is in the form. A bb has no reason to go past a technical max whereas a straight power lifter may on occasion (shouldn’t be often at all) lift the absolute max they can regardless of form breakdown.
all of that said, if your responding well in line with your goals then obviously your doing exactly what you should be(and based on your pictures what you do works),
as ever in this game, the one certainty is that there isn’t a certainty in what everyone should or shouldn’t do
