Fire homunculus vs Wind homunculus in r5

Hey guys currently farming essences to switch my water homunculus

Looking for the fire one eruption for r5 or the wind one magic bullet madness

My current team is Chasun dias front

Im planning to remove hwa and put in the wind or fire homie

Anyone here using one of the homies and can tell me which one is better? And if it's worth to swap out hwa for one of the homies
