before i purchased my 550F, i was looking at other honda CBs, the other CBs were mostly twins though... however, i did consider the CB750 as well, but its weight was atleast equal too if not greater than my old CX500 and i wanted something lighter, and more agile, that could work as an all purpose daily rider and touring bike, so i settled on the lighter, more agile 550, though i still wish it had the aftermarket the 750 enjoys
