Good dimmable LED bulbs from quality manufacturers like Philips dim very well with many incandescent (leading edge) dimmers. Usually these bulbs are larger and have space in the base for a driver circuit that derives a brightness signal from the waveform rather than passing through the chopped current. Smaller bulbs with no built-in driver are much more suited to dimming using a trailing edge dimmer or dedicated LED driver. These strobe like mad on a traditional dimmer switch but may benefit from having a single incandescent bulb on the same circuit to round off the waveform a bit. For one difficult circuit I put a 5w ceramic resistor in parallel with the lighting to smooth out the dimming response between two different fixtures.
