That's a big difference in price, but I do wonder about the overall performance and longevity of the one with the crimp connector. Any thoughts?

"If" your ECU runs flawlessly, keep using it as you won't loose any performance.
Here you can see the correct setup:

Just get an universal BOSCH heated lambda narrowband sensor 0 258 986 502.
the two white wires will be connected to GND and switched 12v (best would be using a relay driven by the same 12v as the WUR, as then the sensor heater only gets power if engine is running.
The black wire will be connected to the wire of the OX-Sensor plug (crimped, not soldered).
