Since the quality of the product has been addressed by others, I want to speak to the question of impression.
Personally, I dislike vinyl in a residential setting and I dislike the appearance of peel and stick even more. Though, if I am honest, a good part of the difference in opinion comes down to the quality of the installation.
As to the impact on potential buyers, I would think a solid surface (like real, if cheap, tile) would get the house sold quicker. (Notice I said quicker, not for more money) But it all comes down to the market and not just how hot it is. Try looking at Zilllow for comparable houses for sale in your area. What do they have for flooring? If most of them have peel and stick, you are good. But, if many of them have solid surface at the same price/features mix, well those are the kind of houses potential buyers will be comparing your house to.
Even better if you have a friend who is a realtor or a relationship with a realtor you plan to use to sell you can ask them about the flooring in your area in your market segment.
