I will chime in.
2years ago I had a 40B and had the Noopsyche lights. they had fantastic color pop and great shimmer and had great color and growth on my corals. I went from a radion g2 pro to the Noopsyche. My acros in that tank grew well and colored up well. At least till the Dinos killed them all

Fast forward to today.
I have a new tank that is a Reefer 350. I had 2 XR15 G4 lights on my tank. I decided I wasnt going to spend the money to add a 3rd XR15 after the disappointing par results I got testing them with a apogee 510 meter.
So I bought 3 noopsyche lights and got them yesterday and put them up. its been 2 years since I had them but I will say going from the XR15 to the Noop lights. all my corals pop way more and that is with trying to replicate the same color I was using on my radions.
Also the tank has a more 3D look. I dont know if its from the shimmer or what but it has more depth look vs the Radions for some reason the tank looked flat.
the controller leaves alot to be desiered. Once you get the lights dialed in you dont really need it much and they are great lights
