It's really an apples and oranges comparison between the two. The Fox Stage 2 System comes with 2.0 coilovers and shocks, while the ICON Stage 2 System comes with ICON 2.5 coilovers and 2.0 rear shocks, since ICON does not make a 2.0 front coilover. The Fox 2.0 system is much more geared for general truck purposes and will give you a nice ride on pavement while still being able to handle moderate-duty off-roading. The ICON Stage 2 kit is more performance-oriented and has a stiffer street ride, but can handle more aggressive off-road applications than the Fox Stage 2 system.
