What's a higher priority, DD comfort or autox performance? Are you comfortable test and tuning damper settings and changing spring rates? Are you building a competitive scca car? Just local events for kicks? What kind of tires will you use?
imo neither will be great off the shelf for a competitive autox build, the springs are too soft. There's more potential in theory for the kw v3 because they are double adjustable, but that means more ways to get it set up wrong than right, I've heard that the Ohlins are more comfortable (maybe the most comfortable on this platform) but that may hold back ultimate performance. Sorry no direct experience with either but I've looked at a lot of setups for autox and there's not much off the shelf that's appealing imho. For a dual duty car where autox competitiveness isn't the top priority you'll probably be happy with either depending on where you personally land. If you want a more competitive setup there's other options but some have been successful on re-sprung V3's.
