Question about acrylic tank corner edges

[JESTERX626]

I've only ever seen acrylic tanks with 2 rounded corners at the front, and sharper edges in the back. My bro said he's seen acrylic tanks that have four sharp corners and said that they are stronger. My stance was that the standard 2 round corners and 2 sharp back corners was better, if any two corners would ever leak it would only be the two in the back, not four.

What do you guys think? Which build makes a stronger acrylic tank?

It would depend on how the rounded corners on the tank were made. If the acrylic was bent to form the corner, then it would be less prone to fail, but not necessarily stronger.
