Walking inclined will most likely burn a "higher percent of fat" from your total kcals. This will burn less kcals than running, however more of the kcals you burn will come from fat. This is because oxygen is more readily available.
Cycling will burn less kcal than walking if HR is equated. This is because you are using less musculature.
Fat burning is going to depend on your intensity and duration of the activity more so than the mode you choose.
If you are looking to retain LBM and decrease fat, I would go with walking or cycling (lower intesnity, longer duration). If you just wanna lose weight/muscle/fat, run like Forrest.
