Dr. Strange at least made sense as super-invincible, because his enemies also were.
Black Panther is what happens when the rule Marvel applies to create new villains ("more of the same, but STRONGER AT EVERYTHING") affects a character too much. Black Panther does some genuinely cool shit every now and then, but for every Skrull Invasion of Wakanda you get a Silver Surfer or Mephisto fight.
Sure, Batman gets hit with the same whenever he's working with the Justice League, but it's easier to forgive him since he's not so Batgod on his own stories.
