I would be embarrassed to tell you how many pairs that I own.
I am picky with jeans also, but I go for comfort just as much as style . ( That changed with aging.
) I am not a size ~0~ , since being in the womb. 
My take- The brand runs large, especially the "super-stretch" versions. In BM stores- if it is a super skinny fit - I wear a 10 . IF it is a regular fit - I wear an 8 . In a boyfriend jean , I wear a med , or an 8 . It just always depends on the cut. I like a "fitted jean," but not a "poured in" look.
In super stretch, I wear a 6T. When I first put them on , a perfect fit, but they do stretch out. My true size would be a 4 T- that had been worn. 
In other styles, it is a hit /miss. Sizing is anything but consistent. If you find your size, you will love the comfort. Finding your size, is a real pain.
It seems to me the quality is not what it once was, but it is still "decent."
** Also want to add, I am NOT apple shaped, I am hourglass. Have no tummy, but have junk in the trunk.
