Slow Progress is better than No Progress.

Super frustrating just looking at the thing every morning sitting in the car port.

A couple of things to consider. There is a real problem out there with cheap knock off sensors being sold in Bosch and other OE packaging. The quality manufacturers are playing Wack-A-Mole trying to shutdown the counterfeiters.
Second is O2 sensors are sensitive to voltage fluctuations. The OE'S supply them with stable voltage from a power conditioner that is usually built-in to the ECM. Most aftermarket stuff just hooks them to the battery directly exposing them to all the voltage drops and spikes associated with starting the engine.

Good luck.
