There will be less flex from the F250 leaf springs just because of how thick and stiff they are. That was what I needed because I want to help my towing stability and help increase my payload capacity. (Official numbers be darned.)
If you do ever decide that flex is more important in the F150 -Deavers are the only real option I know of. For around $500-600 Deaver will make a set of individually thinner, 8-10 leaf spring pack for the you. Having the thinner individual springs give the rear end a remarkable amount of travel for how basic the F150 setup is.
I have never used them but I have always heard good things about the company
