Hello, I would definitely go with the glass mosaic as shown. Did you consider herringbone crema marble?

That first one would be a nightmare to clean food off of - spaghetti sauce flecks and whatnot.

The glass mosaic you posted is too busy for your countertop. I'd look for a tumbled travertine in a solid light creamy color (pull the tone out of your slab) or a solid color subway tile.

I like the strip mosaic but think it may be too much pattern in the long run. Have you considered a plain tile backspace with a strip of this mosiac running through it? Something in a soft beige or gray.
