Seeking Feedback Re: Ansuz vs. Shunyata or Synergistic Research Power Conditioning

I’m currently using the Shunyata Research Everest in my HIFI system and attended the Florida Audio Expo this weekend. They were many rooms using the Ansuz conditioning products. They appeared to really work well… In addition, the synergistic research room also displayed a very solid power conditioner. The images from the systems using the Ansuz and Synergistic research appeared to be more lifelike… And holographic… No rooms were using the Everest. Considering making a change and wondering what the thoughts are out there for best power conditioning.
