For some reason the Narex set looks more "robust" as the hornbeam handle on the sweetheart seems fragile...but after looking around more everyone says the sweetheart chisels are better than the narex. They seem to be identical to the ones on LV as on amazon for 30% less.
Both the LN and the current Stanley chisels are modeled on the Stanley 750 chisels from the past. That is why they look alike.
