Does anyone know how the transcend sdhc 150x compares to the kingston. Kingston seems to have class 2, 4, 6

Are these industry standards or kingston standard? I am hesitant to purchase transcend before I understand the differences. I am gonna be booting off this thing, I am thinking the class 6, looks like the way to go?

OK, I now see that transcend also has a class 6 4 and 8GB card.
