How closely do mcu actors match their comic book characters?

The only verified source supplied concerns the animated series X‑Men '97, which details voice actors and their roles in that series. No information in that source discusses the Marvel Cinematic Universe (MCU) actors or compares them to the characters in the comic books. Because the evidence is limited to X‑Men '97 and contains no data about MCU performances, it is impossible to assess how closely MCU actors match their comic book characters based solely on the supplied facts. A reliable comparison would require additional sources that specifically analyze MCU portrayals and the original comic book characters.
