Whoever posted this is probably just out to cause fuss.

Half those brands are at least decent student instruments, a few are professional quality ones.

OK you reccomend Artly but not Armstrong, they are made in the same factory with the same parts. Another company buys a blank flute and stamps it with thier name. They are exactly the same(newer) models. Look in a parts reference guide for Armstrong flute parts and it will tell you to "see Artly" There is no way you can judge one over the other.

The old model of Armstrog flutes before the merger were actually a bit better than Artly.
