um...Bowser's recovery is beastly. It has great range, not too much lag, and you can change it's trajectory depending on what angle you upB and how you DI using it. It isn't excellent, but it is in no way like Roy's...
Falco's recovery sucks. it can be gimped easily (the ->B can be n-air out of, and falco is always going to be too close to the stage using upB--easy to knock him out of)
Doc's recovery isn't as bad as people think. He drifts well, has the cape (to stop his momentum and provide a slight boost the first time), the down B, his upB and his gimpy magnetic hands. He can also disrupt edgeguarders using pills or the down B. It still isn't a good recovery, but again not on the same level as Roy's.
Roy's recovery is extremely predictable, short, and easy to edge-hog (to ledge-hopped punish if he upbs onto the stage) It's like doc;s ,except he falls faster, doesn't have a downB that helps his recovery, and doesn't have an attack that can force people off the edge.
