Mineral glass cannot be buffed once it is scratched and it does scratch fairly easily. Acrylic scratches if you breath hard on it, but it polishes out just as easily with a bit of metal or plastic polish.
Sapphire is tough to scratch, but aesthetically it is dead when compared to the warmth of acrylic. I like to wear acrylic, I like to abuse sapphire. Mineral glass comes in last.
