Regular led bulb > regular incandescent imo They fail less and have less duds out of the package(in my extensive experience) and don't heat up to dangerous temperatures (which causes many issues beyond the fire hazard). They also use 1/10th of the power The positives for incandescents are that they don't dim as much over time and they are cheaper to make. The things I care about as an electrician are the things in column A.
