No doubt that good quality energy saving bulbs last long, have almost no warm-up time, do not turn blue after half their lifetime anymore -all that is history, tales from the beginning with the early generation of such bulbs. However, the one main problem I have with them is light colour. even warm white ones do not transport enough red frequency waves, but tend towards a certain poisonous yellow-green, which distorts colour reproduction significantly, and also looks bad to the naked eyes. If somebody tells me that is not true, I must refuse that by pointing at the fact that I am talking about physical solid facts: the gas elements used in these bulbs and brought to shining physically are not capable to carry the frequencies that transport the red coloured part of the light spectrum. If you say the light looks like normal bulbs, then you are seeing things that physically are not there - and you might want to check with your eye doctor.
These colour distortion that especially become obvious with object including red colour components (they fade) make these things very annoying for me.
And if you really want to save energy on large scale in your household, skip energy saving bulbs and go LED all the way. I use an Ixon IQ front light on my bike, a single diode light that is. The range and brightness of it as well as the focussing of it I did not imagine before starting to use it some months ago. It beats every strong halogen-handlight (Maglight and such) hands down. But again, gemütliches White for your living room is a problem for LEDs to produce, too, they are either blue-white, or bright-white like snow. thats nice at a working desk, but not when sitting in your living room and enjoying the company of friends, or reading a book.
