Your normal bakes don’t look too problematic to me. Like Shawn says, minor bake errors can be acceptable.
One thing I will suggest is to increase the resolution of your outer ring using the bevel tool:

There’s an imbalance between the inner geometry and the outer (more inside, less outside). Also an imbalance of high poly details on a visibly jagged ring. I think baking on this updated geo will prove a nicer final result.
