I'm trying to make the substantive argument that the J-20 has an operational advantage over the F-22/F-35/B-2 due to less stringent maintenance requirements.
No, because of your lack of experience, ignorance, and arrogance, you have no substantive arguments.
Do you know the initials A G E ? No, it has nothing to how old you are. The initials stands for
Aerospace
Ground
Equipment.
Here is the source for the F-35's AGE support...

Do you see how portable they are ?
Next...If you had bothered to perform basic research for the keywords 'f-35 flightline', you would have found plenty of images where the F-35 is parked
IN OPEN RAMP. You would also find that in some instances, the jet is parked under a covered shelter for some maintenance.
So when we take the portability of the jet's ground support equipment and how it can be parked outside the hangar even for maintenance issues, your claim that the J-20 has less stringent maintenance requirements is nothing but vapor.
Your source, which as usual you do not understand...
http://www.aviationpros.com/article/10943391/how-to-supply-power-and-air-for-the-f-35
...Is where the jet requires more in-depth maintenance, such as 'depot level' maintenance, of which the J-20 as the same levels.
Note this paragraph in your source...
The F-35 hangars also need to be multi-squadron ready. For instance, a Harrier squadron could occupy the F-35 hangar at some point. This aircraft, like most of the other legacy fighter aircraft, is based on 400 Hz power.
This facility is required to be multi platform support capable so that means it has to modify its equipment to supply the F-35's DC power system. That does not mean that every time an F-35 needs some maintenance, it has to go into this specialized hangar. I explained the three major levels of maintenance a long time ago. Can you find it ? Or were you asleep in class when I made that post ?
You want to cheer for your China and the J-20 ? Go for it and have fun. But if you are going to bring my country into the discussion and if you are wrong in
ANY way, just as I have in the past, the consequence is that I will bury you with knowledge, facts, and the truth that no one, not even your friends, can save you from embarrassment to the silent readers out there.
