A picture of the cabinets and kitchen would help.

I would go with lower left also. I have black granite in a bathroom not a fan

Thanks. I just want their to be a nice contrast

If you like cleaning, choose black, shows ever fingerprint, dust particle, and smudge. Choosing the one gray one in the front is a safe choice as it is very similar to your current counters. The stone int the back far right would be a good choice. Gives you change, has contrast, but does not seem to compete with you cupboards or backsplash.

If you want to tie your cabinets in try the the one at the top that has black, orange or whatever the color is ! I think black spots easy. I have granite in 4 areas of my house and the black gives me the most trouble. I have to get a razor and run it around sink . To get spots off

I think I'd go with top middle if it looks really nice with the cabinets (that's important). I like the lower left too, but it has quite a bit of a yellow tone and that will be exaggerated with a big amount of it.

The top middle, although your backsplash might be too white for it. I think I would do the backsplash with the granite too. Run it all the way up the wall.

Top right. Gives you a little contrast.

Top right corner

Yeah, top right isn't bad. It would be my second choice. It does work a little better with the white splash than top middle, so if you decide for sure to keep that splash, top right might be best.

Front left would be first choice. Top right is in second place if you keep that white tile (which I think is too harsh a color with your warm cabinets).

Top right or a darker granite (I'm a fan of dark granite), I find the top middle and bottom left would make everything look a little too orange

I think top middle

I think middle right (2nd one from the top on the rightmost side) as it has the wood color in it and not too busy at the same time. In my opinion, the grain pattern stands out in Oak and so a calmer, contrasting counter top looks good.

top middle is what I would choose! Easy decision ;-)
