Straight vs curved Efan blades.....

I am going to ordering some efans soon and building my own fan shroud, however does anyone know the difference between using straight blades vs the curved ones? I have looked up the specs and it looks like the CFM between the two are close.

Thanks in advance.

Thanks for the replies, I read that curved fans are quieter but flow roughly 10% less air. I decided to go with some straight fans. I ordered one 14" and one 12" fan. I wanted to get 2 14" fans but they won't fit on the shroud I am making....

I just wonder how loud the straight fans are..... I guess I will find out shortly....
