No I haven’t tried those conditioners. Just very content with what I have now.
Glad to hear that your PS Audio power re-generator works well for you.
But that does not mean:
Power conditioning is sometimes helpful but nothing beats a PS Audio power regenerator.
Your PS Audio power re-generator is designed differently than Audioquest's Niagara power conditioners, and differently than Shunyata Research's power distributors.
They all attack power issues from different directions. And they also have overlap -- perhaps in grounding for the connected equpment and surge suppression, etc.
For example, the Audioquest and Shunyata boxes have huge power reserves, to handle instant power transient demands.
The Audioquest and Shunyata boxes stop noise, that is generated from each stereo's box, from traveling to the other stereo's boxes. I do not know if PS Audio's re-generators have circuitry that does the same?
I have heard good things about all of the above choices. I wish that I could audition each of them to hear which one takes the win.
I have heard the Shunyata Research Everest power conditioner, and it is amazing. But I have not heard the others. So I will not declare a winner.
This is a good review of Shunyata Research's Everest 8000 model (recently replaced by the Everest X model, for which I found no reviews):

It is a long read, and it is an informative read. The second-to-the-last paragraph summarizes the box's prowess.
Finally, there is the warranty. The Shunyata Research Everest has a lifetime warranty (noted in the review). I do not know what warranty the Audioquest and the PS Audio have.
