That is purely a matter of taste.
Tile baseboards are more robust when it comes to moisture, scratches, or dirt.
They can also be produced relatively inexpensively from leftover stock or offcuts.
With the help of, for example, stainless steel profiles, the tile baseboard can be enhanced somewhat.
With baseboards, you can create more contrast in a room. But also in terms of design, there are more alternatives with baseboards.
They are also relatively quick to install and can be replaced if disliked.
One should be careful when installing baseboards. There are click systems or just simple strips. In both cases, watch out for possible pipes in the wall. (e.g., water-carrying plastic pipes for conventional radiators or frost-proof outdoor taps).
