The first one sounds more like Scarlet Johanson to me. It's not just about the voice itself, it's about the sensuality and gravitas of the voice. The first one has Scralet's warmth and feminity whereas the second one sounds a robot impersonator trying mimicking scarlet's voice without understanding emotions.

So to me you really proved that the voice actress sounds more like Scarlet than a literal AI replication of Scarlet. If that's now damning, I don't know what is.
