dji Mic vs Ulanzi J12 vs HAPPOYEER wireless mic system - Is expensive better?

I compare the audio quality of the DJI Mic, Ulanzi J12 and the HAPPOYEER USB-C mic set. All sets contain two transmitters (mics) and a reciever. The case charges the components too. The DJI Mic can be used on any camera (and many computers) as it comes with a 3.5mm jack, an iOS lightning adapter and a USB-C adapter. The Ulanzi J12 comes with an iOS lightning adapter (receiver) only. So this version (there is a USB-C version) can only be used with an iPhone/iPad. The HAPPOYEER is comes with a USB-C receiver. The DJI Mic displays the audio levels and the input levels can be adjusted. The Ulanzi J12 and HAPPOYEER do not have any displays nor input adjustments. You can monitor the DJI Mic via the 3.5mm headphone jack. One downside of the HAPOYEER and Ulanzi J12 is that you cannot monitor the audio unless the device you are using (or app) displays the audio levels. The DJI Mic can record audio to both a camera/device and internally to the mic (very useful). While not a big issue, you have to turn the mics on for the Ulanzi J12 and the HAPPOYEER, with the DJI Mics just taking them out of the case activates them. This is a time saver. The HAPPOYEER has built in noise reduction and the Ulanzi has the option to turn on noise reduction. Both the receivers for the Ulanzi J12 and the HAPPOYEER don't need to be charged as they draw power from the device. This is not the case for the DJI Mic.

Due to the different connections I've tested the following:
DJI Mic tested on iPhone 13 Mini & DJI Action 3
Ulanzi J12 tested on iPhone 13 Mini only
HAPPOYEER tested on DJI Action 3 only.
