First let me preface that I HAAATE granite. Our new home has granite tile (even worse) on the counters and the master bath has granite on the vanities. There is a seam there and it is noticeable.
I think the most important thing is to find a good installer.
I had a friend do a semi-speckled black and there should have been almost no visible seam, but it was done poorly.
I've seen granite that was put it so well, you can't tell were the seam is.
Look is important, but more important is how easily it will clean up, wipe up and not pit or chip.
I would sell my mother to gut this granite and as much as I would not say laminate is my first choice, the newer ones are AMAZINGLY pretty and easy to care for and cheaper than granite (in some cases). Plus if you drop something, it won't break
