Well, you can infer that since I encouraged another package what I think of the lifts you mentioned, I'm familiar with the packages you mentioned.
Old Man Emu does not give a lift amount though some of their vendors do. An OME package will "lift" the vehicle dependent upon the springs selected and the weight loaded on the vehicle. If you want a 3" lift, you should get adjustable coil overs so you can dial in the 3". I got over 3" with OME 885/N140 front, 895/N17e on the rear, with a Demello steel bumper and Warn winch up front.
The best "bang for your buck" is the components installed that don't need replacing or upgrading. You do know that putting a lift on and taller tires will NOT make the FJC handle better, right? I'm not sure I'd put that skinny of a tire as the 235/85/16, but I do think the 255/85/16 is the best size tire for the FJC. The BFG KM2's in 255/85/16 is a great tire IMHO.
But, back to your original question...not a fan of spacers or ProComp, but that is just me. Sorry to not answer your question. Good luck with your decisions...
