A thinner blade will penetrate deeper and the thicker blade will bind quicker on softer wood. Especially if we are talking about clean cuts through > 1.5" diameter branches. The thicker blades will encounter more resistance because the whole width of the blade is required to pass through the medium.
The advantage slowly tips towards the thicker and heavier blades as the material gets harder and the penetration becomes more shallow. The wedging effect in this case tends to help split and shatter the harder wood. The thinner blades will tend to bind more in this case because of the slightly deeper penetration with no wedging effect.
Here is what a thinner FBM will do to soft wood.
Looks pretty good to me
