For me, I wish I could have the upper from the KD9's fused with the midsole/sole combo of the LeBron 14's. I like the fit of the KD9's a lot more (not as wide, and better lockdown), but I think the full zoom bag is not super springy, and has some dead spots in the fore foot. With the LBJ 14's the upper sucks for me personally, it's thin/unsupportive and I have to hammer down the laces and strap, and still don't get a great lockdown/fit, but the midsole/sole combo is very nice, and has great traction and bounce. The bottoms of my feet are sore after a full session in the KD9's, but not in the LBJ 14's. So kind of a tough question for me, both shoes have their flaws, and both have great aspects. I would recommend trying each on in the store, because for me and a lot of the reviewers I have seen, the lockdown/fit was the make or break point for each. But I would warn you not to be deceived by the look of the full zoom bag in the KD's, it looks a lot better than it is, at least was for me. And a few people on my team have had the bag blow out, which can happen to any shoe really.
