here is an image of my tile.
I have this in my kitchen, master bath and foyer.
I like the way it looks, but its a PITA to clean.
it does not have a smooth feel to it, so when you sweep or swiffer, etc. some of the 'dirt' stays behind -- especially hair. mine is long and my dog sheds to beat the band.
but in this image, you can see where the rug sits [where the color changes in the grout] this was from the Master Bath -- the kitchen is much worse.
[now lets hope i figured how to attach images]
as mentioned before .... sealing is very easy - this is the first house i had tile in and we did ourselves. But depending on how MUCH tile you have to seal, when time is money - it may be worth it for you to hire out. otherwise, get a few family members or friends to give you a hand for an afternoon.
