We live in southern New England and IMHO tile tends to be too cold for our climate. Down south, it is fine, even welcomed, but here in north it gets cold in the winter unless you install radient heat under it. Also, tile can be tough on the feet if you are standing on it for a long time and if a dish falls, it will definitely break.
That said, we have hardwood. We too were advised by everyone not to do hardwood in the kitchen 13 years ago before it became really popular to do it. Now every new home has it. We love it. It is beautiful to look at and warm and comfortable on the feet. I would not have anything else. Our 13 year old floor is looking a bit beat after years of abuse by kids and our dog, but we can just have it refinished whenever we want and it will look as beautiful as the day is was installed. I love the warm look and the warm feel on cold inter days too.
You are the one who is paying for this, so install what you like. Good luck. Jay
