I've worn 501's for most of my life and have never found anything that fit me as well.  The denim weight and quality of constructions are probably less than they used to be but I haven't found that a compelling reason to purchase something else.  Buying these online has become a bit of a challenge however.  You're now faced with a plethora of finishes with cute names that really don't look that different from one another in a website image.  You might see a difference in a store but online it's take your best shot and hope you like them.  That being said, I was happy with these.  They had a nice slightly faded, worn look to them.  I find the ageing usually looks a little artificial but these weren't bad at all.
