LP leather is the nicest and softest in my opinion. I used to like Coach, way back when they made quality pieces. I think they've gone in a wrong direction, I don't care for any of their logo bags and I've been hearing a lot of folks having quality issues.
I own many LP bags now, and have never had a quality issue.
Plus, I like that fact that I can carry my LP and don't see the bag coming and going everywhere I go. Coach is very popular here and it's all you see. I like carrying something unique.
