Which piece is stronger?

Main Question or Discussion Point

I'm trying to decide whether to add material to my piece in this location and if it will make it stronger.
The piece is attached to a plate and will experience a horizontal rotational force. Will adding that extra piece in the design make it stronger?

I would be more concerned about strengthening the thin section between the hole and the top radius on the component .

I'll have to look into that as well, but there shouldn't be much force in that direction.
