I'm not gonna go as far as saying which is "better", but I would highly suggest getting the NOSS head. I'm pretty sure the NOSS head is cheaper, and I can guarantee you'll get great service through dlnoss. Aside from that, by picking up a NOSS head, you'd be helping out a fellow HQ member.
I'd PM dlnoss to get a price quote, his service and quality of parts are outstanding.
