Yayyyyy and only THREE no wait TWO days late!
Yyyayayyayyyyyyyyyy!!!!!!!!!!!!

Okay!
The RESULTS!

(Original challenge was here btw)

Scoring was my own subjective opinion.

1: WTF-15 by NavalGunnery

Here

This aircraft FAR visually exceeded what I had ever thought possible within the restraints of this challenge. It looks stunning, better than even the best I've built under NORMAL CONDITIONS.
As can be told, it is based off the F-15 Eagle (though as this isn't a replica challenge this has no bearing on its final "score").
The techniques used truly impressed me and I still can't really believe this was done on all-stock parts. Bravo.
Even if some proportions are a bit.. odd.
Now, it should be added that, while visually impressive, the flight performance... ain't great. It's more fun to look at than it is to fly.
Still, it looks so good that it won the challenge regardless, that much was obvious.

Things got tougher from here.

2: Unprocessed Ducky by 11qazxc

Goodness that name is a mouthful...

Here

Now, I should note beforehand: I only just tested this, so perhaps there's some bias here compared to things I'd flown weeks prior.
Still, I think my ranking stands regardless.
So, I know what you're probably thinking: This thing looks like it was half chewed by a shark and thrown in the garbage afterwards.
And yes, it is a rather... video-game-specific design.
Nevertheless, it did something I was absolutely not expecting:
A supermaneuverable aircraft in the Unprocessed Plane Challenge.
Yeah, that thing at the front? It works like the canards on New Pigpen.
Despite it's simplicity, I received nothing else like this, and actually learned something about supermaneuverable planes.
The paintjob is obviously just based off the predecessor aircraft, but clearly this thing didn't care about looks, only performance.
So, for being so unique to other competitors and for its honestly admirable function-over-form design, it sits comfortable at second place.

Deciding on No. 3 was toughest, I think.
Still, I think I've made my decision.

3: Unprocessed Mig25 (reupload) by Yish42

The original had an altered cockpit, but was allowed to be modified and resubmitted since it was only a visual change.

Here

While not the most visually impressive craft by the end, it was before long overtaken in that sector, I just find this one fun to fly. Sure, it's not very good at being a MiG-25 seeing as it turns like a biplane, but again, this ain't a replica challenge so it don't matter.
Good fun!

Honourable mentions:

MiG-29 Fulcrum by HuntleanWarlordI

Here
Has a few issues leading to it not making the podium, but a valiant effort at a replica nonetheless. Reminds me of the WTF-15, though not as advanced.

Mogg-21 by BARREND120

Here
Another replica. Unfortunately has a rather mind-boggling symmetry issue in the wings causing it to roll. I... don't even know how that could end up in there. For that reason, it is here but not up there. Still looks good, though I've some criticisms on some visual choices regardless. It's a tad blocky.

PMCG Corporation HiC-II (Hoevercargoe it CRAHS Model.II) by Monarchii

This one is strictly a mention, as I'll explain.

Here
So, there's a story here. The original was disqualified for having modified engines. As it was a functional rather than aesthetic change, this craft was wholly disqualified. However, Monarchii submitted a modified form before I was able to inform them of this, so it kinda sits in a limbo state. Had it qualified for the podium it would've been given a special "fourth place", leaving whatever position it would've otherwise had for a properly compliant submission. That didn't happen, but I do still find this modified form enjoyable enough to fly, so I'm putting it here regardless.

That is all, I think!
To everyone else who submitted a craft, thank you. Some were quite good, some were... perplexing, and, uh, some...
Well, they were there.

Ahem

So, thank you for reading. Unless you just skimmed, in which case begone!
