I think the stam has been out for a while... the neverfull is more casual, you can wear it with t-shirt and jeans and it would look cute. If you're into dressing out and going for nice dinners, then that stam is your elegant bag. Both bags have tons of replicas but it's really nothing to worry about in my mind, because if replicas were as good as the real thing, then nobody would be paying the big bucks anymore. I always prefer nice leather, so the stam would probably win (although I'm a huge LV fan).
