What are the this / advantages of porcellaine and ceramic tiles

Especially:

Is it really more difficult to lay porcellaine - why

Which one is more robust / does not show scrates easily

Thanks guys

Porcelline tile is more dense and can be used outdoors and in. Ceramic is fine for most every installation but you need to be aware of the rating system so you know the weariblity. 5 is the hardest/strongest ceramic. I do not fine either to be more difficult to install. Where are you doing the tiling and what is the sub floor?
