The reason most build LW instead of BC is for positioning reasons. Most organized teams do not stand idly while you stack BC counters, and Carries need to change targets constantly to stay away from being caught off guard. To some extent, champions who disregard safe positioning may benefit from BC (Like bruisers tanky enough to disregard incoming damage).

Another point in favor of LW is the team comp. If there's only one main source of autoattacks, while the rest of your team prones to AP damage, then BC counters would only benefit one person (yourself), and a LW might be better. Instead, if you have a Shyv jungling and an Olaf and you 3 decide to target one single champion, BC will definitively improve your damage.

It's not only the numbers that matter, but you have to factor the playstyle. As an AD carry, I almost never buy BC instead of LW due to the fact keeping myself safe usually means I have to switch target every 2 hits (Meaning only one stack benefit).
