It could be just my biased view/experience.

I worked for a chinese startup in Beijing and we barely employed git or reviews, massive projects had 0 tests, we put 0 thoughts on architecture, just stop when it works.

I joined an established European company after that and the difference was huge, I had to relearn everything, proper code reviews, follow best practices, you don't stop when it works, you stop when it works, it's well tested (extensive business tests plus at least one required integration test for every change you make), iterated over the architecture a few times to have something simple to understand and clean.

I was also a contractor for another very new European startup where the process was not as robust but still better than the first one.
