There's no such thing as the best floor overall: there's the right one for the room and for how you live in it.
Porcelain stoneware
Durable and easy to clean, it works anywhere. Wood-look versions are now very convincing.
Parquet
Warm and pleasant, it needs a little more care. In bathrooms and kitchens it's best considered carefully.
Resin
Seamless, with no grout lines, very contemporary. It needs precise installation and a perfect substrate.
