I agree, I've seen them side by side and there is a big difference. This is what I noticed most. Looking at the edge of the starfire glass through 18" of glass I was able to read the label on a tank sitting behind this one. When you look at the edge of regular glass all you see is green. Of course it won't be as noticeable in 3/4" , but you should try and compare the two side by side. Does it justify the extra expense? Depends on the person and the budget, but if it was me and a tank that size ( your masterpiece tank) I would do it. Unless you plan on getting a bigger/ better tank down the road. Compare the two side by side and that will help "clarify" the situation.
