At first glance, Fancy Footwork and Acrobat seem pretty similar in that both deal with euro, cradle, hop step, spin, and half-spin layups.
Despite this similarity, the difference appears in that each badge boosts these shots during different phases during the layups. The differences are as follows:
Acrobat boosts spin, half-spin, hop step, euro-step, cradle, reverse, and change shot layup attempts.
Fancy Footwork boosts the gathers on spin, half-spin, hop step, euro-step, cradle, reverse and chance shot layups.
The subtle difference is that Acrobat will increase your chances of making that set of layups, while Fancy Footwork only triggers the animations on those layups.
Recommendation: Both are great badges for any slasher or guard, but we see Fancy Footwork as the more effective badge. Acrobat, while effective, overlaps with other finishing badges such as Consistent Finisher.
