I would use the brighter one to give amazing contrast to the cupboards. The other is pretty too and is a warmer feel but I prefer the contrast

I would choose the top piece. It has beautiful colour and works nicely with the floor and paint choice..Is it granite or quartz?

Both go very nicely. I prefer the lower one with more white in the background. It feels fresher.

I love the top piece it pulls everything together.

Depends are these just for perimeter cabinets? Will there be an island also? If everything else is going to be fairly calm (i.e. not an overly busy backsplash), I would be inclined to go with the bottom sample. I think visually it is more striking and could be the statement piece of your kitchen, assuming as previously stated, that it's not competing with a busy backsplash.

The top piece for sure. The warm tone of the floor is missing in the other choice and would fall flat in the space, in my opinion.

While all 4 of these kitchens are lovely. I think the countertops in the first 2 pics bring more to the table, so to speak, than the countertops in the last 2 pics. Like most of decorating, it's really going to come down to which one you prefer as you are the one who is going to have to live with it.

I like the bottom one- it just seems less trendy, it is timeless to me.

They are both nice and would be fine. I know you can't tell from the small piece, but I'd go see the actual slabs they would be using and go with the least busy of the two.

If they are actually granite, then make sure you see the whole slab before making your final decision. If those are quartz, I like the bottom one better.

The top granite works better with the floor and cabinet, but you might have to change the paint color to pick up the cream tones in the top granite.( I hope my laptop is showing the stone colors right) My advice take a pic of floor along with cabinet sample and top stone to Ben Moore and they will help you find a more complementary paint color.
