My opinion has always been...
"Use the Battlemaster as your basic Fighter because it really ain't that hard to understand. Especially if you give the person the most basic of the maneuvers."
And if the player is still incapable of understanding how to use the Battlemaster and really just wants to use the Champion because it's "the easiest"... then they aren't going to care if the Champion isn't supposedly "as good" as the Battlemaster. After all... if they really cared about class and subclass comparison, they'd actually bother to learn the game and the rules that come with it in the first place.
