I'm not going to argue against the fact that the Chinese firms can't and don't do better than American firms (because they can and do do better in many cases), except that it's impossible to know how much or to what extent Chinese firms have financial (or other) backing from the government there. It's an open secret that many "strategic" industries get varying levels of support, often under the table.

BUT: However they got there, DJI is so far ahead on the consumer/commercial side I can't in good faith recommend any alternatives unless you're doing work for the federal and some sensitive state-level government entities.
