I'm going to reply to that post in the same manner it was written, although also sober.
Ummmm, not a mark on him ? What about this...
Or this ...
Using allusions would be tough to take down Tony, given that allusions are a literary device.
Maybe you mean "illusions". Anyway, he didn't use illusions on Tony, but then his illusions don't have to fool Tony, they have to fool the super sophisticated electronic sensors that are built into the nanotech suit.
How long did Loki last against Thanos with 2 infinity stones before being straight up killed ?
On that showing alone nanosuit Tony is orders of magnitude tougher and more capable than Loki.
Also, whether Loki went full out against Iron Man ( mark whatever suit Tony wore in Avengers) in Avengers doesn't matter, because Loki is now up against a suit that took on Thanos one on one, and made him bleed.
Comparing relative feats of characters, who have not definitively fought each other is the best rational method for determining the likelihood of who will defeat the other. On the above, observed feats Tony almost certainly defeats Loki. So yes, how the MCU portrayed Loki is directly relevant. Up to this point he has fought Frost Giants and Thor, which is impressive - but the nanosuit fighting Thanos is a lot more impressive.
Finally, the character in the image you provided is MCU Loki, he's who Loki would have been had Thor died in the 2011 film . Therefore MCU Loki is the correct point of comparison - clearly distinguishable from comic book Loki.
