New Counter Tops

We need new counter tops since the old ones were ruined while we (John) were installing our new stove;))). Picking them out is harder than I thought. Here are pictures of the condo for me to use while looking for them. The slab of granite is what I think we will use.
I don't have any experience with selecting stone counters. The website Houzz has been helpful but my confidence level is low especially considering the expense.
