Honed Bianco Carrara marble. Beautiful to look at and very tactile.
Lovely in every way except for cost. Not cheap sadly. That said you could end up paying as much for Silestone types as the marble.
If you're accident prone and worried about staining etc, don't be. Marble is pretty robust.
I've previously had stainless steel. I rate it highly. It was amazing too. Extremely durable. And easy to keep.
For the next kitchen in my next house, I'd happily have stainless steel or marble again or granite.
I've had wood and granite years ago. Granite was fine no issues at all. Wood as much as I love it, was quite hard to keep nice. Stains from cups etc and dark patches around sink.
My mum has corian and loves it. She thinks it can do no wrong. It is lovely to look at and the seamless sinks do look fab. Bit plasticky to touch though but that's just being picky.
Quartz could work well if you find something you like.
Bear in mind that quartz joins very badly and its very obvious whereas real stone (marble granite) joins so much better.
To be honest, its mostly down to what you like the look of and what your budget is and how you feel about maintenance (wood etc).
