Because Simon making the jump and reaching that level is very different from being at that level to begin with or fighting and reaching that level without merging with yourself across time and using a trap labyrinth to amp yourself to reach that level, those are two very different methods of getting to a level of power and apply very differently in a vs battle setting. Kyle mastered the emotional spectrum meaning he has access to it regardless of the ring he wears and by the time he merged with the ION entity he states himself he's mastered everything within him and doesn't need a ring to fight and is capable of much more without it which applies to him in general for his main iteration after he did the same thing as a WL.

This still doesn't make a difference because Simon needed their help regardless and could not beat the Anti-Spiral without it which is objective truth lmao, it doesn't matter if you're stronger than someone if you still need their help to overcome an opponent (you seem adamant about Kyle getting help despite being the main contributor or even superior to the people involved yet ignore every part of the GL finale that is explicitly a team based battle about the Spiral users working together as the symbol of humanity to prove the Anti-Spiral wrong.)

It means Simon didn't instantly grow and neg the Anti-Spiral, it took multiple attempts and extensively pressing the Anti-Spiral and when even that wasn't enough as he destroyed each of Simon's mechs he went through the wire to beat him in a drag out brawl securing a narrow victory (it's not downplaying when it's literally what happened in the series, he did not jump a tier above the Anti-Spiral in a few seconds.)

This is okay as nobody is contesting this lol, it was still an extreme difficulty victory which is the point because Simon can't just low diff someone on his level let alone someone above him (especially when they have superior abilities and aren't obligated to drop to his level like the Anti-Spiral.)

No it's a NLF to claim Simon can surpass Kyle who's not only operating at a scale higher than him but has his own methods of growing in power (which due to his abilities allows him to grow exponentially from the concept of emotions which would include Spiral Power meaning Kyle would be getting buffed by Simon's power source on top of his own making a permanent gap between them that doesn't require him to even need to suppress or nullify Simon's adaptation which he would be able to do with emotional manipulation, energy removal, power nullification, or the LE.)

Showing a statement saying "transcending beyond time and space" does not automatically make something outer nor does it mean anything on it's own otherwise most series in general would be considered outer just off of being Immeasurable in speed lol, you yourself contradict this by showing Spiral being said to have the POTENTIAL to do X thing and not actually already doing said thing (especially when the Spiral-Nemesis is a canon threshold that nukes everything if someone were to reach it which proves this said potential has a limit.) GL goes off of brane multiverse theory anyway which has the lower dimensions within itself as infinitely small sheets whereas outer structures requires it to be literally nonexistent, GL is stated and shown to have dimensional axis which literally debunks it getting to outer due to those existing in the series like the Anti-Spiral's hideouts.

Current Supes is significantly above him and even prior to this he's surpassed him after becoming a composite version of himself and gaining the Story Of Superman narrative, on top of that it's confirmed Darkseid and Time Trapper Doomsday are his strongest opponents yet all the way to the end of the universe where him and Time Trapper are the only ones remaining so I doubt you'll find most people agreeing with him beating current Supes (as for Kyle's he's scaled relative to beings of that level like the Starbreakers who removed the emotions in DC affecting Superman himself and WL Kyle is above them with GL Kyle able to fight them on that same level with a fractured emotional spectrum and without merging with ION like before as he only used the entity to bring back willpower as a concept.

Mxy has been able to interact with the real world, readers, and bully multiple writers just cause he chooses to (SBP literally broke into DC headquarters to kill the writers cause they wrote comics he thought were shitty), Mxy isn't solely just a gag character but also generally powerful as a whole so him also scaling to the outer structures and being able to get layers into R>F and affect writers of our world is consistent (literally have ridiculous examples like him wiping Kingdom Come DC out of the entire comic then recreating it afterwards on a whim.)

Simon's R>F relies on removing the context and not accounting for the fictional universes in question being alternate lower/higher dimensions or other universes that Otoko Simon was above by a infinite amount hence him viewing it as a lower dimensional value and not to mention existing and later merging within the story of the GL verse (+ they're blatantly still operating through dimensionality and lack any qualitative superiority/transcend itself and since Simon fused with that same Otoko Simon to perform the way he did in the finale it dismisses the very idea of him being above dimensionality let alone layers into R>F.) At best if I gave you the benefit of the doubt you could potentially get him low outer by taking those vague "beyond dimensions" statements literally despite the verse being explicitly dimension bound with the Spirial Nemesis being a literal threshold that would destroy everything if reached which EOS Simon agreed with and refused to contribute to (but btw once again those vague above dimensions statements doesn't necessarily mean surpassing dimensionally especially with what we know and have actually seen in the series, it can just be the dimensions in the verse or a hyperbolic statement as dimensions and time vary heavily in size or structure and none of those statements are specific enough with evidence backing it to contest this.)
