Lower cost and only one stop vs. a chance for OZ F. Tough choice; if QR is novel for you, then I would strongly consider that.
Even though end-to-end journey time is the same, shuffling through one airport versus three is a significant advantage: Connecting through BKK is not much fun, especially if you don't have access to the TG F lounge (would you on this itinerary with inbound F?), and the international-to-domestic connection in ORD will be a real pain, possibly involving a train ride, and with likely long lines to get to your TSA encounter.
I love the ultra-long flights like QR C. Of course that part of the journey won't be quite the same as the OZ F experience, but it will be nice, with a fully-flat seat. Plus entertainment should be better on QR.
