This list is nonsense. The entire abysmal tier is wrong and missing some characters.
ZSS should be higher [until someone can explain to me how to contest the hitboxes on her down+b without some specific projectiles, she recovers for free against a ton of the cast].
Wario should be higher [obscene airspeed, waft is amazing for recovering, he also has bair if he's backwards, and can use his down+B too].
Sheik should be lower until her up+b is patched [it currently has zero I-frames IIRC].
DK should be lower - you can shine spike him or dair him with some characters extremely efficiently with practice. Not great defensive options to protect himself offstage either.
Snake should be higher - he has great aerials, a plethora of explosives to extend his recovery, and solid armor on his up+b [I know it beats Fox shine at least]. Unless this stuff was patched [I don't know how Snake was changed in 4.0 BC, if at all].
Pikachu's recovery should be higher, unless it can also glitch choosing two directions [because up and up diagonal are usually more than enough, and Pika has QAC as well as JC thunder for protection].
Ganondorf and Captain Falcon belong in the abysmal tier - mostly awful hitboxes, very linear recoveries, easily intercepted all around. Bowser probably belongs with them, as he lacks stalling moves like DK side+b and has a very easily intercepted recovery.
Lucas has a tether and zap jump, should be higher.
Ivycopter [like ZSS down+b] is almost uncontestable without projectiles, should be higher.
Puff's recovery is not good if spiked more than once, but she has such good airspeed that it shouldn't happen, and rising pound is quite helpful as well. I think simply holding up with tap jump on also automatically meteor cancels as fast as possible, and if that's true, her recovery becomes much more meteor smash resistant. She also can walljump now, which helps her recovery further. She should be much higher.
I'm sure I take issue with more than those, but I'll point them out for starters.
