Blocks- copy instance vs. insert

I have created an block instance, no problem there, but now want to use it in my scene about 100 times. I have inserted it once. Do I need to “insert” the rest of the instances or can I just copy the existing instance multiple times( drag+alt with gumball)?. I did see mention of “Block Copier” script but not sure what the advantage of using that is.

Hi Randy- Copying will work fine.
