The Soma brand tends to make their forks out of Tange Infinity tubing which I think is meant to be lighter, and being curved would have some theoretical damping due to the nature of the curve. The Carver is based off the old Kona P2 fork designs, which are nice forks too, and having a midfork eyelets is pretty nice.

If it were my money I'd probably take the Carver, I have a P2 Kona at 410mm on an old Mongoose and I think it's great. Save the money for more fun parts.
