On my team there are two people with CS backgrounds (one PhD, the other MS). There are a couple of PhDs from the physical sciences and one from a more Software Engineering academic background. Without exception the guy with the SE background produces generally better quality code. The CS guys are not arrogant, they know their CS stuff, but their ability to develop software is... underwhelming.
