Maximum effect with minimum means

I’d like to propose a "challenge" to you based on a recent feature on Adweek.com by Mehmet Gozetlik. Gozetlik argues that less is always more when it comes to advertising, especially products’ packaging. Below are variations of the packaging for well-known, international brands. I’d like to know which versions you find most attractive and/or which versions you think would be most effective in selling the product – the original packaging, the simpler packaging or the simplest packaging? Is a minimalist packaging design more aesthetically pleasing or are the "bells and whistles" essential?
