I generally don’t really mind clusters, although the clusters on Atlas Obscura don’t seem to dissolve and instead remain visible, which did throw me off initially. But I do strongly dislike some implementations, where (de)clustering happens very frantically, when switching between zoom-levels. However, rendering all points does looks quite clever, but effectively also creates clusters in high-density areas; which is ironic. Perhaps that in such areas you might as well cluster, to create some sort of middle-ground: with either a count or heat signature to more clearly discern density.
