I personally like CFL. They are more efficient, don't get as hot as incandescent bulbs, and unlike incandescent bulbs, you can actually get light that approaches white. Also they're much less bulky and easier to handle than traditional (lightsaber-shaped) fluorescent lamps. What's not to like? Also, each bulb contains only a few mg of mercury. Tuna has ~0.3 ppm of mercury, so if you eat two pounds of tuna then you'll ingest about 0.3 mg of mercury. I don't think you'll ingest more than 10% of mercury even if you break a CFL, so roughly speaking, "breaking a CFL" is the same order of magnitude as "two pounds of tuna" - doesn't sound that dangerous to me.
