users say this one actually gets up to the 30MB/s rated during use with a DSLR and i dont want a card unless it can beat my current class 6(and looking at the numbers it could have been marketed as a class 10) and this is with 3.26GB in use across 436 files:

(aware both your posted have better write, but also have worse read)
went with this because its still 8GB(which is plenty, and the 16GB version is $95) and the class10 Extreme is the newer version (Extreme III C6 is older)
