IMO, the best comparison videos on the internet. No biases, no shilling, even no actual recommendations. Just does the work and you make your own decisions. I've watched every video he posts

I was technically more interested in the loading of the caps than I was the center breaking. I have not, and likely will not, ever buy universals that are drilled for anything that moves serious power. I'd rather have ungrease-able or ones where each cap has a needle zerk.
Most I saw fail, that weren't drilled, I think it was the needles getting crushed or the surface of the trunnion failing. Tack welding the caps in place definitely helped on S44 joints.
There was another machine I used across campus that I probably shouldn't have used... to measure heat in the joint running it at high RPM. Speculation was that you'd cook out the grease, gall the surface of the trunnion, and start eating needles. At the time Magna had a machine there for testing birfield/cv for some senior design project. Anyway, I can tell you that running a joint at high rpm above about 7 degrees really heats it up fast. I only ran two, a Neapco Brute Force and I think it was branded an "Extreme" from Spicer.
As far as I can tell, as long as the joint is secure and kept clean internally they will take a lot of abuse up to whatever limiting designs there were.
