Physics2D.OverlapCircleAll vs OnTriggerStay ~ PERFORMANCE

So i'm currently creating effect/damage temp areas, where any character passing over gets damage over time / slow etc, i'd like to know your opining about using Physics2D.OverlapCircleAll() on Update() to detect characters in range VS OnTriggerStay() in terms of performance, usually will be 0 to 5 characters on these areas.

Thanks in advance <3
