I must respectfully disagree with the comments in
BOLD.
Priest (Vol 3) and Hudlin (Vol 4) did focus on T'Challa's scientific/engineering creative abilities. It was BP's wealth, political power, AND scientific/engineering creative abilities that makes him comparable to Tony Stark. If it was just his strategic mind set and not scientific/engineering creative abilities, he would be more akin to Cap.
Twice in the issue were Storm & BP go to see Doom on their Honeymoon does Hudlin showcase T'Challa's inventive mind (see images below).

Priest & Hudlin both built on the fact that T'Challa is an polymath genius who invents cool stuff, who rules over a country of warrior geniuses who invents cool stuff (not every citizen, but he has access to the best engineers & scientist geniuses who invent cool stuff for him & the country lol).
My two favorite comic characters at this point are T'Challa (No.1) and Tony Stark (No.2). I do not really want all of their personality traits from the MCU to bleed exactly into the comics.
Shuri (or Taku) can build T'Challa tech, but he should be able to build/invent his own gear when the need arises, as was done in Rise of the Black Panther.
Everyone knows Batman can build his own gadgets, but the writers over time stated he gets a lot of his gear from Wayne Enterprises. I would think because it saves time on Bruce having to create everything (Read " Under the Hood").
As a leader Black Panther should delegate work when appropriate [ which is how Priest and Hudlin wrote majority of their BP comics], but T'Challa should not be striped of his inventive abilities to try and sale comics. Quality writing should be applied to sale comics.
