That's like saying Steak is Steak so eatting Chuck = Rib Eye. Levi's are stiff and crappy feeling. The jeans I wear are so soft they feel more like cotton than denim. While I wouldn't wear $400 jeans, I do get ones that cost considerably more than Levi's, and imho they're worth every penny. Even the relaxed fit Levi's just don't feel comfortable. Are they worth the money? That's a matter of opinion, but the jeans I have on right now, there's not a pair of levi's that are even close to feeling the same when worn. I paid all this money for comfort, just like I paid a lot more for the tires on my car so I can have a smoother ride. Some people don't care about shit like comfortable jeans and a smooth ride though *shrug* A good indication you're wearing shit jeans is if you bought them at a store that also has a supermarket (Target, K-Mart, Walmart etc) The crazy thing about Levi is, you can find styles that run 70-80 bucks. I have 1 pair of 550 "relaxed fit" I got with a gift card, they were $72 and they're utter shit.
One big difference is how the denim's treated, I will say Levi's probably do hold up a lot better than the brand I buy, but I'll take comfort over durability any day of the week. And a lot of females look at a dude who wears Levi's like the dude who wears Star Wars, and other graphic tee's with non sense on them. Very few things say "I don't really give a fuck about my appearance" like wearing jeans you bought at a mega store.
Wrangler's are even worse than Levi's, as as a few other cheap shit brands.
