You're probably not going to get any good recommendations unless you can
tell us something about your application.

GFS and GFS2 (like OCFS) are clustered filesystems that work at a layer
above shared block storage (iSCSI, FC, etc.) SAN.

NFS (like CIFS) is a distributed filesystem that does not require any
shared block storage or SAN appliance.  GFS and NFS are entirely
different.  NFS works well for some purposes, for others a clustered
filesystem is superior.

Note that you can export a GFS filesystem to mount it remotely with NFS
or CIFS, so the two are not mutually exclusive at all.  That can be a
good approach to build a fault-tolerant NFS service as well.
