Mariner in Lower Decks is far more immature and makes far more questionable choices, but she is a beloved character. I think Burnham’s issue is that she has the emotional stability of a high schooler. You can have immature characters, you can have characters that disrespect the chain of command, you can have characters who make lots of mistakes; but you can not have characters who have a mental health crisis every other week.

Discovery is like a Star Trek show if nearly every character was some version of Lt. Barclay; crippled by their own insecurities and forced to overcome them again and again without ever seeming to actually grow out of them.
