Well, I think you need to purchase a kit of that plane & report back to us your impression of what YOU get.
From what I see of that thread, that gentleman could work from plans with the best of them.

I would have no problem with saying that AZM is up with the better kit providers IF their business practices were up to what is considered acceptable and their product was approching the quality of Proctors.
At this point it is buyer beware on both points.
If the product were up to better standards everyone would put up with unacceptable business standards and long waits, but it's not.
Let's face it, it's hard to make a good living in the model business alone hence the avaiation display company. That's also why you will not see any more improvement in the kit contents in my opinion.
