"Better" is a comparative term: "X" is better than"Y". "Y" is less good than "X". Simple, clear, obvious. 
As in men and women are equal as persons. Ooops. Bad example. Doubt is erased when Jesus reportedly said:"Mary has chosen the better part".  If you don't mean what you say, say what you mean. 
How many times to I have to TELL you :)
