Ok, so from what I know and heard...
Start with Bilstein, known as comfortable and once high quality, seems like they tend to fail prematurely and the overall quality seems to get down in the last few years, depending on load and vehicle specs they tend to bottom out because of the way they are valved
Fox always known to be more on the sporty side, try to get a deal on the remote reservoir variety, they have an inch more travel (as most remote reservoir shocks have more travel at the same body length)
Overall never heard anything negative about fox shocks.
Falcon ... Yes the Falcon, teraflex is doing something right here, whenever I talked to someone who switched to Falcon shocks from anything other said it was a huge improvement, HUUGE, is what they said, if Falcon the 3.2 would be the best deal in my understanding.
