Zwift Calibration Same Effect as Tacx or Different?

My friends, I have a Flux 2, and I was told that after I unplug it, and leave it unplugged for over an hour, I need to calibrate it when I plug it back in. I can do it on the Tacx app, or through Zwift. My question is, is the Zwift calibration process as good as the Tacx app calibration process? Like, can I just keep calibrating it through Zwift and not have any problems?

Thanks all!!

Zwift recommend you use the manufacturer’s calibration tool over theirs as a preference.
