I prefer the bottom with your cabinets. Yes, the slab is busier but it will not necessarily look like that in your kitchen. I think it provides interest and I like that it has pops of white throughout... and provides some warmth to the white.

I don’t like the color of the top one with your cabinets.

Not a fan of grey in general, but I like the second photo with your cabinet. A much more interesting stone. I would make sure to use the white veins when they cut the counters, as they add interest and pick up your door color.

The first photo is boring and the colors don't complement each other.

Before you make a final decision ask that they pick up the slab and take it outside, so you can see it in natural light with your door. Warehouse lighting is notoriously bad!

The gray one!

Remember that the counter calms down a lot when it's horizontal.
