It has been a while since I looked into it but from memory the advantages of LED are primarily lower power usage and lower heat output. The disadvantages (lifetime of LEDs, growth rate of plants, expense of LEDs) outweigh the advantages at the moment though things are rapidly improving on that front.
Personally I've used large 125W CFLs and they're a very nice compromise of heat output, energy efficiency and plant growth.
