Destructibles - mesh swap or not

I’m working on destructible assets using geometry collections and nanite. My question is, would there be any significant performance difference between using the original static mesh and swapping for the GC when “killed”, versus just using the GC all the time? My instinct is that having the static meshes loaded initially would be more performant than having the GCs loaded all the time. However in my testing I’m not seeing much of a difference in realtime performance.
