I'm not really sure what you're asking, especially since all those granites seem to mix similar colors. Maybe you need to show them next to the vanity color (presume you're keeping) and/or the paint (if you're keeping)...

Thanks, I'm replacing the countertop with granite and these are a few samples. I'll take a pic with them next to the cabinet/tile.

Because the coloring in these three granites are so similar being able to see the large slab may be helpful to help you decide. This way you will be able to see the pattern and movement and how it varies in different slabs.

I vote the middle option too.

Thanks, I think I may go with the middle option (Sierra Ridge). Any advice when looking at the granite slab? Should I select the portion of the slab that has strong pattern and movement?

I like the middle option too. When looking at the granite slab, it's best to talk with your installer about where the cut outs for the sinks will go, so that you can consider this and make sure you see the parts you like in the finished design. If there are any flaws or imperfections in the slab(s) you choose, you can also discuss with them how best to make this work for you so they're hidden and/or cut out in the finished product.
