They work in completely different ways. Here are the practical things:
Compact fluorescents - easily replace present incandescent bulbs, widely available, pretty energy efficient
LEDs - many require unique fixtures, very expensive, very energy efficient, very long life
Right now, for most people compact fluorescents are an excellent choice.
In the future LEDs may be better, but right now they're more a "bleeding edge" thing for early adopters than a practical way to light your house. It would take a very long time to get your money back.
Note that compact fluorescent light bulbs actually REDUCE mercury pollution. This is yet another "logical" argument that is refuted by scientific data.
Fossil fuels contain mercury. Using incandescent bulbs causes more mercury to be emitted from power plants. More than the tiny amount (0.005 grams or less) that is in a CFL.
It's better if you dispose of old CFLs properly so that even the tiny amount of mercury is not released. But, no matter how they're disposed of, CFLs reduce mercury pollution.

If you want to "get rid of" CFLs, you should get rid of conventional long fluorescent tubes first. They contain 2-10 times as much mercury.
Don't believe in hype. Insist on facts.

I also have a passion for hard-drive storage devices and programming, the compact fluorescent light bulbs give off a "happy" mood light that I crave, so I stay near them.

CF Lights contain mercury. While this is only a small amount of the toxic heavy metal, compound this amount with the number of bulbs in use.
Soon there is going to be problems with this mercury finding it's way into our water systems.
We should end these bulbs now.
LED's are safe, bright, and are non toxic.
