If you search, you will find threads about Emeralds. Many players really love them. I have one on a shaft. I was told it was more like a Medium Hard rather than a Medium Soft. I would agree. It plays harder than the Everest that I had, but not as hard as any of my Hard tips. I like it better than Everest (which also a lot of people really like). I haven't played with it enough to have it glaze over. I can't compare it with anything because to me it doesn't have any noticable characteristics like other tips. That should be a good thing, since we're in this to play pool and not to think about the characteristics of our equipment. I think it is worth a try to see if it matches your tastes.
