Lois was hilarious tho. She might have been a bitch, but she was a bitch who kept it real.
Peggy just does anything to keep her eggshell ego floating. And takes any opportunity to stab Hank in the back, either blaming him for shit she started or claiming he did not support her enough when she creates her own problems
Lois would never back stab anyone, she would slap the shit out of you long before that and either straighten you out or throw you out on your ass. She was a master of tough love
