The worm drive saw seems to be a better ergonomic design for either
hand. The handle is well back from the axis of the blade shaft which
should increase leverage for steering a wandering blade. The knob for
the opposite hand is high up so there is no interference of the blade
guard with your arm. I don't know where the trigger lock is but I see
on the other saws that it is conveniently on top of the handle where it
can be operated by either thumb.
Thanks,
