Anne, I love the dark wash ones on you (pic 3), and I think they all look good. I disagree that the creases are a problem. A lot of jeans do that. If we were looking at dress trousers with a more fluid fabric, yes, I would say it's a fit problem. But in my experience, the denim and style of jeans do create some creases across the front that you don't usually see in other pants. (see the finds below, for example)
I have a few pairs of Levis Wedgie style jeans, but here in the US they are actually less expensive than some of the other brands I usually buy. So I appreciate that they are a relative bargain. I don't know that I would pay more for them. It comes down to how much I love the style, really. If you like the other brand just as well, I don't see a reason to pay more for Levis. I will admit to having preferences for brands based on pocket design, so I could totally understand paying extra for the distinctive Levi's pocket if that's part of the appeal.
I don't have a long enough rise to wear ribcage jeans. They are too high for me. Looks like they are a great fit for you!
