Thanks for all of the comments.
I followed the only information that Apex gives officially, and that is on their website:
https://apextactical.com/store/product-info.php?pid67.html
"Recommendation for best function:
Spring Load Bearing for Glock Model 17, 19, 26 and 34 - Glock Item # SP01176 (Available at Midwayusa.com, Brownells.com or Sharpsshootingsupply.com
Glock 30274 Ejector. "
When you tell someone that something is “recommended” for best function, it is semantically the same as saying it is “required” for best function. Otherwise, you’re just recommending that people waste their money on something not needed for best function, and what kind of recommendation is that. 
It seems to me reading comments here and on other sites that there is some useful information on how to use the Apex extractor that Apex is not sharing with their customers directly. There are no official instructions whatsoever- just the recommendation to use the non-LCI SLB found on the page referenced above. The extractor comes with a business card that refers you to to their Youtube channel for installation videos, but none are on the Glock FRE.
So, what you see is the result of someone following the information Apex is providing. If there is more to it, Apex needs to improve their documentation. If they no longer feel that the non-LCI SLB is necessary, then they should take the recommendation off the product page.
It is clear that the Apex extractor works, and it is clear that it performs significantly differently than either Glock factory extractors. My preference, as stated in the video, is based upon slow motion analysis that most aren’t doing. If it was just on what I could see with the naked eye, I’d probably go with the Apex.
It very well may be the answer that many need for their specific extraction or ejection problems. I hope the video gives people considering an extractor swap something to SEE rather than just something to READ about the Apex FRE.
In the end, it could be that currahee has the right idea- maybe all that is needed is reliable cycling and no BTF. Getting picky on what the ejection looks like could be splitting hairs. In that case, for MY pistol, I’d still go with the factory “dipped” extractor Glock put on for free until it performs otherwise.
