What's nice about AB testing is the decision can be made on point estimates, provided the two choices don't have different operational "costs". You don't need to know that A is better than B, you just need to pick one and the point estimate gives the best answer with the available data.
I don't know of a way to determine whether A is better than B with statistical significance without letting the experiment run, in practice, for way too long.
