Incandescent bulbs suck. They break easily, don't last long, and are a fucking fire hazard when used incorrectly (as simple as putting materials too close or putting too bright a bulb in a fixture with inadequate insulation and thin wiring).
CFLs suck less than incandescent bulbs. They don't get nearly as hot, they draw roughly an order of magnitude less current. Are they perfect? No, there are still issues like what to do if one is broken (shattered) and with deteriorating light amount over time on some of the earlier CFL models.
LEDs suck less than CFLs. They draw a bit less power and don't have some of the other CFL trade-offs.
The douchiness is in reactionary fucking morons who scream "waah CFLs suck because of LEDs, therefore we should all go back to incandescents" which is a really fucking stupid comment as you watch them make it.
