I trust the lens rental test much more since they dont base tests on single copies
That as well as the fact that Lens Rentals does their tests with an actual optical test bench while virtually every other test is done with photographing test charts.
Photographing the test charts results in a combination of camera sensor, processing the sensor data and the lens being tested. There's a place for that if one wants to know about that specific combination. but it limits the usefulness when comparing the optical quality of a lens.

True as far as it goes. But well-designed test procedures hold the camera, sensor and processing pipeline constant. At least when comparing lenses for the same mount, these other factors are normalized.
And, I'd argue that even when comparing different brands, the differences seen in lens sharpness are far grosser (and thus far more visible when shooting test charts) than the differences in acutance one might find between any modern sensors having similar resolutions.
