I'll know better when I wear BD. I almost skipped it because I have BP and thought they might be too close. I think the difference is in the formula. There are comparative swatches of BD & BP here on this thread. I don't recall seeing any of the other comparisons that you mentioned. I have FnF & SR and didn't even think of comparing them because I had already decided to purchase BD. If you have enough burgundy lipstick I would put money on the cream shadows.
