Hard rock maple. Mine have lived with us for just over 30 years. They are forgiving, beautiful, and indestructable. They get better with age. The care is simple. I use warm water and DAWN and/or, depending on how I am feeling and what I'm cleaning up, a 1 to 1 combinatin of ammonia, rubbing alcohol, and water (there is a spray bottle full of this stuff on the counter now).
Please be aware that "us" is a husband and two children and all their hungry friends. The hard rock maple counter tops have seen action and the occasional oops. One of my better decisions throughout my life, those counter tops. Not anywhere close to the "husband" one, though.
Enjoy what you choose.
