To answer your question, I'll need to analyze the provided code snippets and their corresponding benchmark results.

After analyzing the code snippets and benchmark results, I can provide a brief comparison of their performance:

1. **recursiveDeepCopy**: This custom implementation seems to be the fastest, with an average execution speed of approximately 64967.4453125 executions per second.
2. **Lodash CloneDeep**: The Lodash `cloneDeep` function has an average execution speed of around 52757.0390625 executions per second, which is about 19% slower than the custom implementation.
3. **Json Clone**: Using `JSON.parse(JSON.stringify(MyObject))` results in the slowest performance, with an average execution speed of approximately 49464.23828125 executions per second, which is around 23% slower than the custom implementation.

Keep in mind that these results are based on a single benchmark and may not be representative of all scenarios or environments.

Please let me know if you have any further questions!
