People may complain that you can't compare the two shows to each other, but with BCS being the sequel, it is going to be compared all the time.
I felt like in BB, you had an idea of the purpose of the show and where it was going in the very first episode. With Better Call Saul, I'm still not really sure where we are going other than developing the main character. While being entertaining, there isn't any real purpose to the show and I don't think I'd be interested if I didn't already know and like the character from Breaking Bad.
