I'd say the Blur is definitely better for the money; you can find them for $65 compared to about $135 for a Military, less than half the price. The Military is significantly bigger than the Blur; that may be good or bad depending on your preferences, but I personally find the Military to be overkill for my EDC tasks.
14C28N is a really incredible steel for the price; takes a very fine edge, and is apparently easier to machine (and thus cheaper), but can still get pretty hard due to the nitrogen. I really, really like it, and consider S30V to be a fairly minor upgrade (trading off a lot of sharpenability for edge retention), but the S30V Blur is much more attractive (IMO) with the flat grind and stonewash compared to the hollow grind/beadblast of the 14C28N versions. If I recall correctly, Kershaw runs their S30V a bit softer than Spyderco, which means you have a little less edge retention, but the added toughness is nice; sharpening chips out of S30V isn't really how I want to spend my time. Speaking of sharpening, the Blur has a recurve, which may make sharpening a bit obnoxious depending on what you use.
The Blur is also an incredibly smooth manual opener if you choose to deassist it.
Basically, if you really want a larger knife, or really don't want a recurve, go with the Military. If not, the Blur is a fantastic deal.
