Tests:

Lodash
const obj = { a:1, b:1, c:1, d:1, e:1, f:1, g:1, h:1, i:1, } const n = _.omit(obj, ['a','d','i']);
es omit
const obj = { a:1, b:1, c:1, d:1, e:1, f:1, g:1, h:1, i:1, } const n = omit1(obj, ['a','d','i']);
compiled omit
const obj = { a:1, b:1, c:1, d:1, e:1, f:1, g:1, h:1, i:1, } const n = omit2(obj, ['a','d','i']);
rest and delete omit
const obj = { a:1, b:1, c:1, d:1, e:1, f:1, g:1, h:1, i:1, } const n = omit3(obj, ['a','d','i']);
babel
const obj = { a:1, b:1, c:1, d:1, e:1, f:1, g:1, h:1, i:1, } const n = omit4(obj, ['a','d','i']);

**Benchmark Overview**

The provided benchmark, hosted on MeasureThat.net, compares the performance of five different JavaScript functions for removing properties from an object: `lodash.omit`, `es omit`, `compiled omit`, `rest and delete omit`, and `babel`.

**Tested Options**

Here are the options being compared:

1. **Lodash`omit`:** A widely-used JavaScript library that provides a simple way to remove properties from an object.
2. **ES Omit (`omit`):** A built-in JavaScript feature introduced in ECMAScript 2020, which allows you to remove properties from an object using the `omit` function.
3. **Compiled Omit:** A compiled version of the `omit` function, likely generated by a tool like Babel, which transpiles modern JavaScript code to older versions that are supported by more browsers.
4. **Rest and Delete Omit:** A custom implementation that uses rest parameter syntax (`...`) to extract properties from an object and then deletes them using the `delete` operator.
5. **Babel (compiled omit):** Babel is a transpiler that converts modern JavaScript code to older versions that are supported by more browsers. In this case, it's used to compile the `omit` function.

**Pros and Cons**

Here's a brief summary of the pros and cons of each option:

1. **Lodash`omit`:**
	* Pros: Well-tested, widely-used library with good performance.
	* Cons: Requires an external dependency (the Lodash library).
2. **ES Omit (`omit`):**
	* Pros: Built-in JavaScript feature, no external dependencies required.
	* Cons: Only supported in modern browsers that support ECMAScript 2020.
3. **Compiled Omit:** 
	* Pros: May provide better performance than ES Omit or Lodash `omit`, as it's optimized for older browsers.
	* Cons: Requires Babel to be installed and configured.
4. **Rest and Delete Omit:**
	* Pros: No external dependencies required, uses modern JavaScript syntax that's easy to read and maintain.
	* Cons: May not provide the best performance due to the use of `delete` operator.
5. **Babel (compiled omit):** 
	* Pros: Can provide better performance than ES Omit or Rest and Delete Omit by transpiling modern code to older versions.
	* Cons: Requires Babel to be installed and configured, which can add complexity to the build process.

**Latest Benchmark Results**

The latest benchmark results show that:

1. **Rest and Delete Omit** performs best with 486282.34375 executions per second.
2. **ES Omit (`omit`)** comes in second with 1320568.875 executions per second.
3. **Compiled Omit** follows closely with 974613.5625 executions per second.
4. **Babel (compiled omit)** has a lower execution rate with 787476.375 executions per second.
5. **Lodash`omit` performs the worst with 2121455.5 executions per second.

Please note that these results may vary depending on the specific use case, browser, and environment.
