Yes to the question of more torque for bagging and mulching.
The Toro's transmission (if it is a self-propelled model) will give out in 2-3 years. That's just the way it is, and you really can't do anything to forestall it.
If you are set on a Toro, get one when they are having the extended warranty sale.
Otherwise, go with the Honda.
We, the unwilling, led by the unknowing, are doing the impossible for the ungrateful;
We have been doing so much, for so long, with so little, that we are now qualified to do anything with nothing.
