NWO WWE, from arrival to Wrestlemania 18, was a good angle. Yea, NWO wasn't booked quite like NWO WCW, but the story they told with Rock/Austin and leading to Hogan's face turn (which worked perfectly) was pretty good. After that it got really bad, but they had at least a solid month or so of decent NWO use.
NWO 2000 had Bret and Jeff Jarrett in front, two of the least NWO-ish guys ever.
