A complex benchmarking scenario!

After analyzing the data, I'll attempt to provide an answer.

**Individual test cases:**

1. **"Benchmark Definition": "myCopy = _.cloneDeep(MyObject);",**
	* **Test Name:** "Lodash cloneDeep"
2. **"Benchmark Definition": "myCopy = structuredClone(MyObject);,"**
	* **Test Name:** "Native structuredClone"
3. **"Benchmark Definition": "myCopy = JSON.parse(JSON.stringify(MyObject));",**
	* **Test Name:** "JSON Parse"

**Latest benchmark result:**

1. **RawUAString**: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:120.0) Gecko/20100101 Firefox/120.0"
2. **Browser**: "Firefox 120"
3. **DevicePlatform**: "Desktop"
4. **OperatingSystem**: "Mac OS X 10.15"
5. **ExecutionsPerSecond**: 
	* **TestName:** "JSON Parse" = 14668.0556640625
	* **TestName:** "Native structuredClone" = 6936.74462890625
	* **TestName:** "Lodash cloneDeep" = 19941.205078125

**Observations:**

* The latest benchmark result shows that:
	+ Lodash `cloneDeep` is the fastest, with an execution rate of approximately 20 executions per second.
	+ Native `structuredClone` is slower than expected, but still faster than JSON Parse.
	+ JSON Parse is the slowest.

**Conclusion:**
Lodash's `cloneDeep` is currently the fastest method for cloning a complex object like `MyObject`. However, it's worth noting that the results may vary depending on the specific use case and environment.
