IF cutting materials without placing them against a hard backing, I've liked how thinner edge profiles hold up (I'm talking maybe 30° or less, inclusive). An edge with thinner geometry is a much more efficient slicer, requiring much less force exerted directly against the cutting edge. That really helps with edge durability, so long as the thinner edge doesn't get slammed into a hard substrate under the material being cut. A thickish edge (>40° inclusive) is more 'durable' in the sense that it's shape won't be altered as severely when contacting something hard. But I don't see much advantage in maintaining the geometric integrity of a thick edge that doesn't cut as well anyway, even when it's 'sharp'. A thinner edge can continue to function well for most real-world cutting tasks, even after the shaving sharpness goes away, because the underlying geometry behind the edge still works. BUT, a thick edge will be immediately blunt and unusable as a true cutter/slicer, for the most part, just as soon as the crisp apex is gone. After that, it's basically just an axe-edge for hacking at stuff. Most of my real-world EDC uses for a 'knife' don't call for that.
