Hi
An airplane is not a car in ground handling. It's a 3 wheel vehicle. Toe-out improves high speed stability, reducing responsiveness in steering.
Toe in and toe out are tuned in the car front wheels. We do it on the rears and have only a front wheel. Plus, there is no traction on the wheels.
From my experience, toe-out promotes less wobbling during take off and more stable in high speed.
Do your testing and have fun

This discussion has not a right or wrong answer.
My SM Cougar was a pita during ground handling until Peter Goldsmith asked me to put some toe-out .... unbelievable difference !!!
I guess toe-out has less tendency to bite when the airplane starts to turn. It's like moving the steering wheel when slipping.
But whatever works best for each airframe would be the proper choice.
And I guess that it has nothing to do with Portugal either !

In the first place, no nosewheel actions by a flight gyro will convert a poor main gear setup for tracking on takeoff or landing but landing is the biggy. Second, MOST issues with tracking involve the main gear brakes on landing. An iGyro is NOT going to be able to counteract that component no matter how many course corrections are sent to the nose wheel. That is why the new landing gear gyros like the Electron G200 can moderate braking on each wheel during roll out with a gyro assist function.
