I'd say there's a good 4 to 5 inches of extra leg room. The seats recline a bit more, have winged headrests, and have footrests. All of this is manual. There is no AVOD and there are no air vents. I personally find them a slight bit nicer than the standard domestic 24F 757's as well as the ex-NWA birds, but otherwise if you can take the widebodies to HNL, do it.
