From that perspective, I would go with what turns you on. Hardwood is good for resale, but hardwood in kitchens gets wet. Can be a problem in the long term. Good quality hardwood is warm and rich. If you dig it, Go for it! What price 10 years of enjoyment? Recommend throw rugs by the sink, and some sort of indicator of moisture under the cabinets near any plumbing.
There are a few other factors in play here. Certain areas of town, neighborhoods and square footage require upgrading in flooring products. If you're talking about a $350,000 home in an upscale neighborhood that you got for $300,000 and will be there for a few years (assuming the market returns which it will eventually), then you absolutely should go with hardwood. It is more durable and sends a more expensive, classier message to the buyer. If you're in a small starter home in a tract housing neighborhood, you could be putting too much money in hardwood and might consider a laminate. There is not, unfortunately, a mathematical formula showing which way to go. It is a judgement call in most instances but wood and tile rather than carpet and vinyl flooring should be used as you move up in square footage and price.
Many agents will come and give their opinion for free if you just make the call. I would always want to have someone ask me what I thought BEFORE they made the decision as I can tell them whether their neighborhood will support the extra expense. If you have pets and children, carpet doesn't last as long and Pergo or some other wood laminate wears well (dog nails) sometime actually better than wood. That said I wouldn't put laminate in an expensive house. Even if you aren't going to sell for several years, the right kind of agent would love to talk with you now knowing you'll be loyal and call them again when it's time to list.
Hope this helps.

Tile (especially Travertine) was being had for incredibly cheap - this is also a good durable material (although you would want to use stone as opposed to clay or manufactured)
carpet does wear and tear fast and thus has a much shorter half-life than hardwood or tile
