In your case, only the breeder and people who have grown out both the BX2 and F3's will know which is better. In my opinion, the breeder is just trying to make their inventory look larger using this tactic. A good breeder will only release the best of their line, not offer a gamble on 2 different versions of the same thing.
There's so many complicated scenarios by which back crosses can be made, and I'm surprised the weed word hasn't invented even more complicated abbreviations to distinguish them. Correct me of I'm wrong, but they never taught us about S1, Bx1, etc. in college level botany classes, so I'm assuming these terms were invented by the weed industry. Perhaps the high dollar value of the seeds forced marketing experts to devise more ways to convince buyers to purchase their seeds.
The weed industry in general is so dishonest, I'm not sure how useful this information is in practice. Theoretically, if everyone told the truth, then such details are a goldmine, but a single lie about the origin of a particular strain, seed batch, or clone can render these details useless.
