links to the exact models would have been nice
2 things I saw different on the trek pages, I dont know what exactly they are or if they both have them but only listed on one. the fuel ex 9 29 says it has a kashima coating on the fork and an aramid bead on the tires but like I said maybe its only listed on one but both have them.
the 9.8 does have a carbon front triangle but the rear is half alum. You may be saving a very little amount of weight but its negligible.
what it comes down to is do you ride where there are large rocks that you may bounce your frame off of or is it more trees and bushes. carbon does not dent like alum it cracks with a good enough impact. an extra $1000 for the carbon front triangle is overkill in my book. with fat tires on dirt the stiffness of carbon is lost and the jarring effect of the alum is softened, + the rear shock absorbs most of the frames ride properties anyways. road riding is completely different, on asphalt ill take the carbon everytime.
just one mans opinion.
