Most people like smooth, creamy bokeh (the first image) which doesn't cause any distraction or bring attention to itself. The most expensive cine lenses all have very smooth bokeh for this reason. On the other hand harsh bokeh does bring attention to itself, and is therefore distracting, but this doesn't have to be a bad thing, it can just be used badly or inappropriately (such as film/video). So to answer your question, neither is the "good one", they are just different. I actually like very harsh bokeh but it's not always easy to use well.
Both images are also from the same lens, a Meogon 80/2.8 enlarging lens! The bokeh is different depending on whether the OOF area is in front or behind the point of focus.
