The difference between VCS and KNN is huge, if you have the time and space to tune it. Seriously, even a double-buffered VCS is nothing compared to KNN. It takes many buffers of varying depth, granularity etc to get close to what KNN can achieve, and even then it isn't as good. See targeting challenges, I believe the highest scoring VCS is Dookious.

I know Hydra and Waveserpent use a combination VCS/KNN gun, which segments on velocity and acceleration but does KNN on everything else. That way it doesn't need a tree, but still runs at reasonable speed because of the reduced data size.
