Let me start by saying I do see you try to approach this constructively, which is cool - so let me try and do the same.
Yes, lower gearing results in higher Torque at the wheel axle.
However, higher wheel-axle Torque, does not by definition mean higher usable acceleration and higher "wheelie-potential". Think of a Crawler type ultra low gearing: will it have huge wheel-axle Torque? Yes. Will it do standing back-flips and win drag races? No.
Why? Motion does not just involve Torque; Torque is just a static property. Motion involves Power... which brings RPM in the equation as well: Power=Torque x angular velocity (sort of RPM, but different unit).
An additional factor that contributes to all the common misunderstanding of how this all works is that the Torque produced by a motor or engine is dependent on RPM, and that PMDC motors have a falling Torque-RPM curve (max Torque at zero RPM, zero Torque at max RPM), which is fundamentally different than with the combustion engines, people are used to driving in their cars.
Finally, typical 1/8 brushless set-ups will have so much Power potential, that traction is the limiting factor in acceleration, not the reduction in wheel-axle Torque caused by higher gearing. Here's some more discussion on what I mean with that:

Like Kms, I'm not here to argue or convince anyone. Feel free to believe whatever you want, collect and process the info that is out there and make up your own mind.
