Nothing I have ever seen fishing had the cool factor of watching a glow-in-the-dark smolt pattern swing down below me and disappear into a lake trout maw. I will always have them and use them when night fishing just to see the takes.

I have become a huge believer in UV materials, especially for trout and salmon. One particular pattern tied with one particular UV color last year so completely dominated every other color it "proved itself" to me.

Fluorescent colors I like, but have not seen them produce radically more fish.

Locally, I would say UV is slowly catching on, especially compared to other places.
