We have solid wood. I can't for the life of me remember what kind it is, but I certainly hadn't heard of it before. It's dark, but I wouldn't say it was what I think of as butchers block type.
Pros I guess are it looks v nice and is v hygienic.
Cons are that you can't put hot stuff down on it, so will need to use trivets and become super paranoid about people with hot cups of tea , and that it does require some maintenance. Ours needs oiling about once every 3-6 months, particularly around the sink where it gets wet a lot.
Still looks gorgeous and good as new 4 years after we got it though.
