On contrary, Slobodan, they all look different.
Personally, out of 140+ available Topaz Impression presets, I use mainly the Impasto painting style, which I further modify by erasing or reducing the painterly effect. Others use water color or oil style, or some of the old masters styles, like Rembrandt, van Gogh or Monet. Or simplified sketches or some squiggles. To me, those options look too smudged, whereas the Impasto has bold strokes and some structure. But the main thing that pretty much everybody likes something else and that's fine. After all, we live in a free country.
Attached is one of my painterly renditions of a Havana street scene. The original photo looked too clinical, but the "painted" version looks softer and to me more appealing.
