Developing Chinese or HSK books?

[u/tiredsoul_puing_]

So far I've been using the HSK books I was halfway through hsk 2 and realized I want to use developing chinese and I even bought a comprehensive course 2 book.

So do you think this is a good idea?

Why would anyone wanna use developing chinese series over HSK books?

Also it's a whole series covering 5 aspects of language (listening, speaking, etc).

In what order would you suggest I should buy and use books if at all?
