5/5.......for ZSS's recovery?
lulz.
Yes, she has the best tether recovery, no questioning that. Yes, she has great horizontal recovery with her flip kick. Yes, she has a good second jump. Issue is when she's far enough below the stage she has to use a tether. Edgehug it as the whip goes up, you don't get pulled down, she doesn't grab the edge. Even with the Boost Upwards, more likely then not, she's not going to have a second chance. And if she does get a second chance to grab the edge, worse case event is that she grabs you as well. It's not the most powerful spike in the world, at least part of the time you can aether back and grab the edge.
Also, (correct me if I'm wrong on this part, I've heard a lot of info saying this is both true and false, so I'm not 100% sure), if she does grab the edge, Dair down along her tether route. If she moves up (this is the part I'm not sure of), she'll hit the sword, and fly down. As long as it's before she grabs the edge moving back up, she's screwed. And thanks to Dair's Sex kick like priorities, if she doesn't move as you fall down towards her along the tether line, she'll still get knocked up and to the side, possibly into a stage spike if she goes one direction. If she goes the other direction, Dair should of been finishing just as you hit her. Aether back, possibly aether spike her, grab the ledge, get the invincibility frames, repeat the cycle.
Yes, ZSS has better recovery then Ike. But it's 3/5. 3.5/5 at best. Not a delusional 5/5. That's as crazy as saying Ike's attack speed is 5/5 because good Ike mainers will use Jab Combo and Nair mainly.
And before anyone suggests that I have no clue what I'm talking about: I get my face beaten in regularly by a good ZSS. Between the Glide Tosses, mass amount of stunning combos, and her air game, I lose 4/5 games by a good margin when I use Ike against her ZSS.
The 4/5 for KO power suggested is crazy as well, not as crazy as the recovery however, and should be 3/5. I don't feel like another argument though.
For the Pit Matchup, sorry. I got nothing in this area except theorycraft, no practice. Though, I can confirm that Fsmash works well against Angle Ring.
