Here is some LED vs. CFL data, a couple years old, but it shows some comparisons of light output, watts required and bulb life length.

LED vs CFL -- Which Light Bulb is More Efficient? | CleanTechnica

The more recent LEDs are getting better at the lumens/watt efficiency, but overall, there is not a substantial difference between the two.

The BIG difference is bulb life length with many LEDs asserting 40,000 - 50,000 total hours. I think the $0.86 cost for a CFL is a misprint.
