Again thanx for sharing in conversation fellas! I really wanted you guys to present things from comics to back your claims, but it's fine, I won't either.
My closing statement, including some of what I've said in another thread:
Tchalla & Tony are really equals in my eyes, but if I was forced to put one above the other I always choose Panther. Why? Bias aside...
1) Feats Outside Of Tech?
This is tricky here because most of their intelligence is shown through what they can and have created. For Tony all, or large majority, of his feats are tied to what he's made his suits capable of doing. Tony's best designs are his suits. No one creates more suits or greater suits than Tony except for maybe Doom. However Tchalla has created equal level suits.
I believe Tchalla has more and superior feats outside of Tech (specifically), but if focusing on just one, I think the most important Feat for Panther in this area is that he created his own form of science: "Shadow Physics".
No other super genius in Marvel has created their very own field of science (to my knowledge). Tony hasn't even shown the capacity to do this. It honestly is not that surprising seeing as how Wakanda is at the top of Science in the world, and Tchalla is it's the leading scientist.
-He's also created "Star Cells" which can actually prevent death lol...
But being fair, every major genius has at least one field where they are superior to all others, so Tchalla isnt so special in this regard.
2) Knowledge & Education?
Tony's Education is not talked about much in comics, in fact most of the super genius schooling isnt discussed at all...
Tchalla is one of the few where it is mentioned.
-We know Tchalla has attended the best schools all of the world. Has numerous PhDs.
-He's further been taught by the most advanced nation in the world, so his knowledge of tech & science in general would have to be greater.
-He has gone to depths that Tony scoffs at...magic & mysticism. Such has always given Tchalla an edge over Tony and other scientists who shun away from magical knowledge.
Overall he's more branches out in knowledge.
3) Tech & Reputation?
If we allow Tech to be included in the conversation then Tchalla's tech in comics, films, and TV shows has always been shown to be better than Tony's. Example (outside of comics):
Earth's Mightiest Heroes
"Wakandan Defense Tech Is Better"

Although Marvel, only in the comics, has regarded Tony as smarter...Tchalla has routinely been shown otherwise by Marvel on all platforms. Such goes into reputation. Everyone knows Wakanda is superior to the rest of the world, and largely that is due to Tchalla.
Additionally:
-Tchalla has outsmarted Tony on 3 separate occasions.
-He's out smarted Doom.
Tony has outsmarted Reed before aswell, and even matched Doom before too.. however Doom has considered Tchalla an equal (Doom War).
-He leads the nation that is the most scientifically advanced on the planet (which again has been shown that he is the leading scientist of the country, and the smartest in the country).
Overall, being fair, the two are by far equals.
