Dji a2 vs cuav v5+ vibration

I am writing from a translator
Good afternoon, I have a large drone 1400mm, on an aluminum frame. Problems with vibrations. Holybro pixhawk 4 flight controller, motor t-m p80 III, prop t-m mf 3016. Friends suggested putting dji a2 because it already has built-in vibration isolation and showed that dji a2 is being fixed with such drones. I look towards cuav v5 +. MAYBE WHO FOUND THESE CONTROLLERS AS THEY ARE UNDERSTANDING VIBRATIONS???. What is better to use dji a2 or cuav v5+???
or maybe I need to pay attention to some other flight controller? which can hold the 1400 mm frame
