They all work pretty well, but some have serrated jaws. (like aviation snips)
Serrated jaws work better on heavier material, but leave ratty edges.
Smooth jaws are better for thin or fine work.

That is talent!
I use to make models in brass and copper.
It's quite enjoyable, but yes quite time consuming too.
Still have all the materials and tools to do it, if time becomes available again.
