As I understand it the SG2 has a thinner edge and is really a fantastic slicer, but due to a higher rockwell the edge would be more prone to chipping. The S30V is not as sharp, but the chipping problem isn't there like in the SG2. This is not a put down on Kershaw, just the nature of the steel.
I own the Blur SG2 and it does indeed have a thinner edge, and I have mine sharpened at 15 degrees per side. I use it often, and have not experienced any chipping problems yet, nor have I read about any. I have read about chipping issues with S30V, but I also own several blade in that steel and have had zero problems with them either. I also have the JYDII in SG2, and it too is a fantastic knife.
If they are about the same price and you aren't planning on doing any woodchopping, batoning, or cutting through wire on a regular basis, I would say to get the SG2. It would also be a little more exclusive, as they made only 1320 of them, if I remember correctly. I'm not sure if the S30V model is a limited production model.
Cutter, would you be able to point me towards the threads that mention that SG2 has inherent chipping problems? I thought I had read/contributed to most posts regarding SG2 in the last 6 or so months, and I don't recall reading about it.
Hopefully one of the more knowledgeable people from the Kershaw forum (OE, Kneedeep, 2brothers, Thomas W) will see this and answer you as well.
Hope this helps and good luck with your decision.
