I actually thought the Samsung ads were pretty smart. Alienating fiercly loyal Apple customers is fine, they won't buy from Samsung anyway. But they push some negative stereotypes and convince their customers that if they want to 'break the mold' they need a Samsung.
However, the products are still poor, a stylus for your tablet isn't a feature it's a failure, and in the end I tend to prefer Apple. But that's alright, I don't tend to base purchases on Ads anyway!
I personally prefer product centric ads. I want to see the product, not unicorns. But, much like political ads, you rarely ever see what's advertised anymore; just 30 seconds of what's wrong with the competition.
The thing that's been annoying me lately is the not-so-subtle product placement. It's not just enough that the main character drives a Ford Taurus, but he has to spend 2 or 3 minutes every episode showing it off to other characters and detailing it's features while a camera pans in close. It's so gaudy! But that's the way it's going I guess.
