Time to go through the usual...
I haven't played a good Pika before so he's probably A but I don't have enough experience to say.
Not uncommon since like ESAM is the most notable Pikachu player and then there's others like Mook and Kenny who probably nobody knows about.
I put Custom Ness in S tier because PK thunder 2 beats about half the recoveries in the game since it knocks people away from the stage instead of into it and goes through enemies so it's slightly harder to gimp.
Fox's Recovery is too bad to put him in A (Then again, I did put Falcon in A, so maybe not)
Ike's recovery is too bad to put him above D
Little Mac's recovery is way too bad to put him above even E.
Melee Falco, Captain Falcon, Fox, Ganondorf, Marth, and ton of characters in Melee had abysmal and at best mediocre recoveries. That doesn't stop Falco, Captain Falcon, and Marth from being the best characters in that game. Same with in Brawl where Falco, Fox, Wolf - ledge sweet-spot issues -, Olimar, and Snake had exploitable or just bad recoveries, but that didn't stop Fox and Wolf from being viable or Falco, Olimar, and Snake from being top/high tier. Their offensive capabilities far outweighed their recovery issues and on paper, Little Mac's abysmal "recovery" - might as well call it a pathetic last move before death - could mean nothing if he outright kills you and never has to leave the stage involuntarily.
If this game was only about recoveries, then Sheik, ZSS, Zelda, Wario, Villager - difficult to just pop the balloons -, Meta Knight, Wii Fit Trainer, Charizard, Greninja, and Pikachu would be the best characters. The worst characters would include Duck Hunt, Falco, Fox, Captain Falcon, Ganondorf, Bowser, DK, Ness, Lucas - hey, he's coming back in 6/14 -, ROB, Shulk, Little Mac, Jigglypuff, and even Diddy would count since his Rocketbarrel Boost is gimpable like the rest of them.
Meta Knight gets no results (as for what I've seen) and his nerfs hit him too hard to be any higher. His juggling and recovery are the only thing keeping him out of E
Ito and Katakiri place well with Meta Knight with Ito taking 1st and 2nd in several recent tournaments in CA. If results were the only things that mattered then Captain Falcon would be a loser since so many players use him only to get barely top 10 with only some exceptional players like Fatality placing top 3. This would also extend to... the entire cast except for Diddy, Sheik, Luigi, Fox, Sonic, and ZSS.
I could see MK winning by two reasons: One, matchup inexperience and being Uair to upB'd off the top. Two: Matchup inexperience and getting Uair to upB'd off the top.
Counterpoints: Mach Tornado is a damn good punish tool and ledge trap. If mashed well, you get ~30% of damage which is almost on the levels of Melee Peach Down Smash stupidity.
Shuttle Loop is so abusable, it's not even funny. It combos from D-throw, F-throw, Uair, can be used OOS, and it is something Captain Falcon would die for (not like he's already dead and squatting in the SSB series... RIP F-Zero).
Meta Knight is considered to have the (second) best Dash Grab alongside Captain Falcon and one of the better Dash Attacks in the game. His Smashes, barring Side Smash, are among the fastest in the game. In general, his moves are among the fastest in the game. Dude has, as you noted, one of the best recoveries. He can, unlike most characters with multiple jumps, harass people fairly well with hovering Dairs if he really needs to. The only things against him is how the game's designed: his stupid hitboxes are still messed up, his lightweight, and his need for precision. Oh, and let's not forget how people constantly, constantly compare him to Brawl Meta Knight, a broken character people begged to be banned and nerfed only to be "nerfed" in Smash 4 and now he gets complaints for not being Brawl Meta Knight. Hypocrites.
Things that go for him include his short height, overall speed, and his natural, if short, disjoint with Galaxia. Look, how about you watch Ito's Meta Knight. By this time, the players know about Ito and have fought him at least once:

Idk where to put Falco. I just stuck him in there because he doesn't have anything too special about him(don't hate on me Falco mains)
If he's not at the very bottom or in his own special tier of Failville, then your tier list is invalid.
Heh, this was addressed more towards the person making the matchups claims, hence the "tentative". No, I'm not going to money match Zero if he plays Bowser, nor the best Bowsers in the world.
Aw, but you could do a "charity money match"; loser's money goes to whatever official charity like the Red Cross, MSF, etc.
why the **** is
in "good" tier
He's clearly the protagonist of Zelda Wii U.
