Incandescents cast a much nicer light than any of the CFL bulbs I've tried. It's a struggle getting a high enough rating on them to actually light the area they're supposed to. The 20w CFL in my living room is worse than the 60w incandescent that it replaced, for example. And they get a lot worse over time (I have to buy them a bit too bright so that they are still acceptable after 6 months). Plus, they take so long to warm up - I have incandescents in the places where lights don't stay on long (under-stairs cupboard, for example).
I've swapped almost all my Halogen GU10 bulbs for LEDs (going from 50w down to 5.5w), and the light temperature is fine on those (different, but not unpleasant), but there is a detectable strobing effect - mostly I can see it around the edges of my vision.
I've not tried LED bulbs for standard ceiling lights. I'm a bit dubious about them due to limited angles of light.
Frankly, if I could still get standard bulbs for ~50p each, I would probably go for those for ceiling lights. It's not worth the standard of living drop (in terms of living with dim lighting) just to save a few pence each month on electric
