I suspect that if you ask your question to 1000 different people, you will get 1000 different answers.
Completely dependent on personal preferences and tastes of the people.
We were just at the tile center today (Schautag).
Our tendency is towards a Mediterranean style - whether porcelain stoneware or ceramic, I can't even say yet. We haven't had a consultation yet.
We are only sure that we don't want a polished surface. We nearly slipped on such a high-gloss tile with shoes on - how is it going to be with wet feet then?
In addition, the floor area will probably have tiles where not every bit of dirt is immediately visible and where the cleaning effort won't be so high.
So much for our initial considerations.
