Asus and MSI are quality products. I currently have a MSI, Gigabyte, and ASUS motherboard and they all run well and have never had a problem. (I'm not overclocking at all, so no comments on that aspect of quality)
It looks like the extra $15 buys you name brand and heat spreaders on the voltage regulators. Since you aren't overclocking I doubt that it is needed.
As for QVL, it hardly matters. Can't say I've ever used one of those when purchasing RAM and I've never had a problem. Just buy any DDR3-1333 and stick it in. When you go to add more RAM just make sure that the new RAM has the same speed and CAS latency and it should work fine.
Here is a 2x2GB set that would work with either motherboard - http://www.newegg.com/Product/Product.aspx?Item=N82E16820313102
