I need the tubular incandescent bulbs as a heat source for my tiny lizards. LEDs simply don't generate enough heat (barely any!) to fulfill this function. Otherwise, I love my LEDs in the rest of the house, as they are instant-on (unlike CFLs) and don't contain mercury (unlike CFLs). If you think they have a harsh white light, I suggest you choose LEDs with a lower number on the temperature scale, like 2500K. That gives a more mellow color of light.
