guard frontier - you guard until your Overdrive is full, and you use the most offensive UBB and other buffs in order to reach maximum damage possible. (takes long time)

auto - you literally just dont care and press auto button. less damage, but faster.

of course, if you want the best FH score, you'd use guard frontier. but some people really dont care and use auto.
