Marketing is tricky, because some pick up for look, others reviews, many for price, and so on.
While it can catch your eye, it does not bring repeat customers. Quality does that. Look at Padron. The standard Padrons have some of the most boring looking bands and boxes. They are good cigars though and sell well. I have had some with great bands, and a high tag, where I would be happy never smoking another as long as I lived.
I find that too flashy is overcompensating for crap quality. The bands and boxes cost money, so if the price is reasonable, they put more into packaging than tobacco and rolling quality.
