His roles are much different compared to Erza, who's utilities are more more defensive such as DoT mitigation, spark mitigation, critical and elemental damage null, evasion and has the tristat buff along with her conversion and crit buff.

Behemoth boosts spark and crit damage, has a conversion buff and even boosts crit rate. If you want an OTK squad, replace Erza with Behemoth since Behemoth's ridiculously low recovery and defense will not sustain heavy damage from hard content while Erza can. If you like to play a defensive role, then don't replace Erza.
