I've replaced literally every bulb in the entire house with the LED's. If you get a good brand (Phillips, Feit, EcoSmart) in 2700k color temperature -- they should be indistinguishable from incandescent. Sometimes 3000k bulbs are labelled "warm", but they are a lot whiter than 2700k and do not look like incandescents. LED's in 4000k, 5000k (daylight), 6000k are awful to look at. Our outside lights were too white with either incandescents or 2700k's, so I used 2500k LED and they look great (that's a flexibility that doesn't exist with incandescents).
I hated CFL's, but am "all in" on LED's.
My deck light fixture, which was limited to 100w incandescent, can handle 300-watt equivalent LEDs in equivalent 2700k color, still using half the energy of the 100w incandescent, and now it lights the whole deck.
The only bulbs I didn't change to LED for a long time were the foyer overhead lights, because while the 2700k LED's looked the same as incandescent at full brightness, the incandescents turn to a softer yellow when dimmed that the LED's would not do. However, Phillips recently came out with 2700k LED's that yellow when dimmed, like incandescents, so now I'm using those. I've convinced a number of people to move the LED -- and when they have the proper bulbs (typically 2700k), none have ever said incandescents look better.
For lava lamps you need heat, so incandescents are the only option. I have some vintage Ballantine Beer lights that are motion lights from an hot air turbine spinning on a needle above the incandescent bulbs -- they spin with incandescents but don't move at all with LED's.
