CIFS/SMB vs NFS

I'm looking for thoughts on the age-old CIFS vs NFS debate. From my [somewhat limited] experience NFS is much easier to set up and just tends to work. Some of my more optimistic Windows friends think that sharing home directories between Linux and Windows would be useful. Therefore, they think I should implement CIFS home directories. From what I've found this is a fairly complicated process and the difference in security features often causes unpredictable results. I guess a lot of this is mitigated when the SMB server is on Linux. However, that won't be the case here. The share will either come from a Windows server or a 3rd party storage manager. FYI, I would want to automount home directories.

I don't want to be an uninformed zealot so I'm looking for any arguments for adopting CIFS.
