I've used both cranksets and you can't really compare them. The KCNC is really good looking and works quite fine, but it is designed primarely to be a lightweight crankset and it has a bit of flex. If you want to put some power to the pedals on your hill climbing I would defenately go for the SRAM. You can loose some weight on the chainrings, but with the bottom bracket, it's probably only possible to shave a few grams by using ceramic bearings. And it will probably ruin your budget too.

Why does Shimano paint their groupsets the way they do? If i wanted fifty shades of grey - I'd buy the book.
