I feel like the same problem exists with catalytic converters given my 1 experience with trying to replace one.
Some things you just have to pay more to pay once.

Not sure of a technical reason, but we used parts store sensors and fought with fuel economy gains. After way too many hours of frustration, we tried OEM O2 sensors as a last resort and -- what do you know? We got the gains!
Cheaper sensors will get rid of a DTC, and the ECU doesn't complain, when everything's stock. But even then, they don't seem to get quite as good fuel economy as the OEM sensors.
Best I can tell is it probably has something to do with calibration.
