I purchased the Vornado 460 to replace my 5350 (when the plug became defective) after several years.  The Vornado 460 is more powerful at its lowest setting than the 5350 and really cools the room.  The noise on the lowest setting is more noticeable than the 5350 (which was very quiet) but the noise level is not a problem and I am a very light sleeper.  It is easy to rotate up and down which is a plus since the 5350 required more effort.  

The only reason I gave the Vornado 460 Four Stars instead of Five is because of the placement of the switch which is behind the fan, which is a little awkward, instead of the side.  But this is not a deal breaker considering all the other features and the fact that this is a powerful fan despite its size.
