What aspect of Philip Burris cigarettes is highlighted as a differentiation from others in the market?

The differentiation of Philip Burris cigarettes from others in the market is centered around the use of non-irritating smoke ingredients. This feature is significant as it appeals to consumers who are concerned about the discomfort often associated with smoking. By focusing on this aspect, the brand positions itself as a more user-friendly choice, particularly for individuals who may be sensitive to harsher smoke. This emphasis on comfort can attract a specific demographic that prioritizes a smoother smoking experience, thereby creating a unique selling point that sets Philip Burris apart from competitors who may not offer the same consideration for the user's experience.

On the other hand, while flavor diversity, environmental packaging, and unique advertising strategies are vital aspects of marketing, they do not directly address the experiential comfort and health considerations that non-irritating ingredients present. This makes the latter a more distinctive feature for the target audience.
