Tests:

Procedural Element creation
var arr = Array(2); var el = document.createElement('link'); el.id='ZInject_CSS_zinject_regexr'; el.type='text/css'; el.rel='stylesheet'; el.dataset.srcprop='href'; el.dataset.src='standalone/reddit/zinject.reddit.css'; el.async = true; el.defer = true; arr[0] = el; el = document.createElement('div'); el.id = 'somevalue'; el.className = 'sidebar'; el.innerHTML = `<div class='sb-handle'></div><div class='sb-track'></div>`; arr[1] = el; return arr;
jQuery Element creation
var arr = Array(2); arr[0] = $(`<link id="zinject_reddit_css" type="text/css" rel="stylesheet" async="" defer="" data-srcprop="href" data-src="standalone/reddit/zinject.reddit.css">`); arr[1] = $(`<div id='somevalue' class='sidebar'><div class='sb-handle'></div><div class='sb-track'></div></div>`); return arr;
Custom Method: document.CreateElementFromHTML()
var arr = Array(2); arr[0] = document.CreateElementFromHTML(`<link id="zinject_reddit_css" type="text/css" rel="stylesheet" async="" defer="" data-srcprop="href" data-src="standalone/reddit/zinject.reddit.css">`); arr[1] = document.CreateElementFromHTML(`<div id='somevalue' class='sidebar'><div class='sb-handle'></div><div class='sb-track'></div></div>`); return arr;
Custom Method: HTMLElement.From()
var arr = Array(2); arr[0] = HTMLElement.From(`<link id="zinject_reddit_css" type="text/css" rel="stylesheet" async defer data-srcprop="href" data-src="standalone/reddit/zinject.reddit.css">`); arr[1] = HTMLElement.From(`<div id='somevalue' class='sidebar'><div class='sb-handle'></div><div class='sb-track'></div></div>`); return arr;

A benchmark report!

It looks like we have a comparison of four different methods for creating HTML elements:

1. **Procedural Element creation**: Creating elements using the native `document.createElement` method.
2. **jQuery Element creation**: Using jQuery's `$()` function to create elements.
3. **Custom Method: document.CreateElementFromHTML()**: A custom method created by a developer, likely using some internal implementation of `createElement`.
4. **Custom Method: HTMLElement.From()**: Another custom method created by a developer.

The benchmark reports the number of executions per second for each test on various browsers and devices.

Based on these results, it appears that:

* Procedural Element creation is the fastest method overall.
* Custom Method: document.CreateElementFromHTML() is faster than jQuery Element creation.
* Custom Method: HTMLElement.From() is slower than both procedural element creation and custom `CreateElementFromHTML()`.

Keep in mind that this analysis assumes that the custom methods are implemented correctly and efficiently.
